Answer:

74,4 litros

Explanation:

Dado que

W = nRT ln (Vf / Vi)

W = 3000J

R = 8,314 JK-1mol-1

T = 58 + 273 = 331 K

Vf = desconocido

Vi = 25 L

W / nRT = ln (Vf / Vi)

W / nRT = 2.303 log (Vf / Vi)

W / nRT * 1 / 2.303 = log (Vf / Vi)

Vf / Vi = Antilog (W / nRT * 1 / 2.303)

Vf = Antilog (W / nRT * 1 / 2.303) * Vi

Vf = Antilog (3000/1 * 8,314 * 331 * 1 / 2,303) * 25

Vf = 74,4 litros

Answer:

The meole fraction of acetone in the outlet liquid is \(x_1 = 0.0072\)

Explanation:

1.

The schematic diagram to represent this process is shown in the diagram attached below:

2.

the mole fraction of acetone in the outlet liquid is determined as follows:

solute from Basis Gas flow rate \(G_s = 10(1-0.012) =9.88 kmol/hr\)

Let the entering mole be :\(y_1 = 1.2\) % = 0.012

\(y_1 =(\dfrac{y_1}{1-y_1})\)

\(y_1 =(\dfrac{0.012}{1-0.012})\)

\(y_1 =0.012\)

Let the outlet gas concentration be \(y_2\) = 0.1% = 0.001

\(y_2 = 0.001\)

Thus; the mole fraction of acetone in the outlet liquid is:

\(G_s y_1 + L_s x_2 = y_2 L_y + L_s x_1\)

\(9.88(0.012-0.001)=15*x_1\)

\(9.88(0.011) = 15x_1\)

\(x_1 = \dfrac{0.10868}{15}\)

\(x_1 = 0.0072\)

The mole fraction of acetone in the outlet liquid is \(x_1 = 0.0072\)

The system's temperature is maintained constant using an isothermal process, which is a type of thermodynamic process. Thermal equilibrium is maintained because heat is introduced or removed from the system so gradually.

Any isothermal process must have zero change in internal energy since the change in internal energy depends on the change in temperature, which is zero for all isothermal processes.

Since the temperature is kept constant, the energy change is zero (U=0). Thus, the work that the ideal gas does on its surroundings is equal to the heat that the gas absorbs.

Therefore, In a closed system, refrigerant-134a undergoes an isothermal procedure at 320 kPa and 40 °C until its quality reaches 45%. Determine the effort and heat transfer needed on a per-unit-mass basis. 2: 40.6 kJ/kg and 130 kJ/kg.

Absolute purchasing power parity (PPP) should hold more closely for items that are easily tradable and have low transportation costs.

Absolute purchasing power parity is an economic theory that states that the exchange rate between two currencies should equal the ratio of their price levels. Or we can say that the cost of a basket of goods in one country ough be the same as the cost of the same basket of goods in another country, after adjusting for the exchange rate. Anyhow, absolute PPP is not always true due to various factors such as trade barriers, transportation costs, and non-tradable goods. Items are easily tradable and have low transportation costs are more likely to follow absolute PPP closely.Some of easily tradable items include commodities like oil, metals, and agricultural products, as well as standardized manufactured goods.

The low transportation costs associated with the  items make it easier for opportunities to com, ase up as  individuals or businesses can buy goods in one country where they are relatively cheaper and sell them in another country where they are  more expensive.

The area under the curve is approximated by trapezoids in the Trapezoidal rule, which estimates the definite integral of a function. The number of used trapezoids is indicated by the subscript in the notations T 2 and T 4.

The trapezoidal rule, also known as the trapezoid rule or trapezium rule, is a method for approximating the definite integral in mathematics, more specifically in numerical analysis.

Trapezoidal rule T 2 gives us the following: T 2 = (b - a) [f(a) + f(b)] f(a + (b - a)/2) = /2 + (b - a) /2 with a = 0 and b = 1 and T 2 = 2.

Simplifying and substituting the values results in:

2 = (1 - 0)[f(0) + f(1)]

/2 + (1 - 0)[f(0.5)]

/2\s2 = f(0) + f(1)/2 + f(0.5)/2

Trapezoidal rule T 4 gives us the following: T 4 = (b - a) [f(a) + f(b)]

f(a + (b - a)/4) + f(a + 3(b - a)/4) = /2 + (b - a)/2 f(a + (b - a)/2) = + (b - a)/4

where T 4 = 1.75, a = 0, and b = 1.

By simplifying and substituting the variables, we get with 1.75 = (1 - 0)[f(0) + f(1)].

/2 + (1 - 0)/2 [f(0.25) + f(0.75)] + (1 - 0)/4 [f(0.5)]

1.75 = f(0) + f(1)/2 + f(0.25) + f(0.75) + f(0.5)/4

We may rewrite the equations above as: 2 = f(0) + f(1)/2 + a 1.75 = f(0) + f(1)/2 + 2a + f(0.5)/4 since f(0.25) = f(0.75) = a.

By dividing the first equation by two and taking that result away from the second equation, we arrive at:

1.75 - 4 = f(0.5)/4 - a\s-2.25 = (f(0.5) - 4a)/4

In order to solve for a, we obtain: f(0.5) = 4a - 9 f(0.5) = 4a - 9.

When we use this f(0.5) value as a substitute in the first equation, we obtain:

2 = f(0) + f(1)/2 + a 2 = f(0) + f(1)/2 + a 2 = f(0) + f(1)/2 + a

We obtain the following by substituting f(0.5) = 4a - 9: 2 = f(0) + f(1)/2 + a 2 = f(0

A PFAS anchorage point for a 6-foot lanyard must be able to hold a minimum static load of 5,000 pounds.

PFAS stands for Personal Fall Arrest System, which is a type of fall protection equipment that is designed to protect workers from falls.
The 5,000-pound minimum static load requirement is based on the assumption that the PFAS will experience a shock load of 2,500 pounds in the event of a fall.

This shock load is due to the force of the fall and the weight of the worker, and it puts a significant amount of stress on the anchorage point. The 5,000-pound minimum static load ensures that the anchorage point can withstand this shock load without failing.
It's important to note that the 5,000-pound minimum static load requirement is a general guideline, and the actual load capacity of the anchorage point will depend on a variety of factors, including the type of anchorage point, the material it's made from, and the conditions of use.

Given that:

Volume of carbide (\(V_{C}\)) = 76% = 0.76, Volume of Nickel (\(V_{M}\)) = 100% - 76% = 24% = 0.24, thermal conductivities of carbide (\(E_{C}\)) = 30 W/m-K and thermal conductivities of meta. (\(E_M\)) = 67 W/m-K

a) The maximum thermal conductivity is given by:

Max = \(E_CV_c+E_mV_m=(0.76*30) + (0.24*67) = 38.88\ W/mK\)

b) The minimum thermal conductivity is given by:

Min = \(\frac{E_ME_C}{E_MV_C+E_CV_M}=\frac{30*67}{(0.76*67)+(0.24*30)}=34.58\ W/mK\)

The MMC of the hole diameter is 10.10 mm. The least material condition (LMC) is the smallest size limit of a part that is acceptable for use.  LMC is the smallest allowable size limit that will still allow the part to function as intended. In this case, we will calculate the LMC for a part with a length of \(35.00 ± 0.15 mm.\)

To calculate the LMC, we must subtract the tolerance from the nominal value. The nominal value is the target value of the part dimension. In this case, the nominal value is 35.00 mm.

LMC = Nominal Value - Tolerance LMC = \(35.00 - 0.15LMC = 34.85 mm\)

Therefore, the LMC for the given part is 34.85 mm.

The Maximum Material Condition (MMC) is the largest size limit of a part that is acceptable for use. In other words, MMC is the largest allowable size limit that will still allow the part to function as intended. In this case, we will calculate the MMC of the hole diameter with dimension \(10.0 ± 0.10 mm\).

To calculate the MMC, we must add the tolerance to the nominal value. The nominal value is the target value of the part dimension. In this case, the nominal value is 10.0 mm.

MMC = Nominal Value + Tolerance MMC = \(10.0 + 0.10MMC = 10.10 mm.\)
