An example of augmented feedback would be a beep or a light that informs the driver when they need to shift gears. In contrast, inherent feedback is the sensory information that the driver receives through the car's clutch, gear shifter, and engine sound, which allows them to feel the speed and the gear changes.

Augmented feedback is information that is provided to the driver by an external source. For example, a driving instructor telling a student driver to shift gears at a certain speed. Inherent feedback, on the other hand, is feedback that is naturally perceived by the driver. In the case of driving a manual transmission car, inherent feedback would be the sound and feel of the engine, which the driver uses to determine when to shift gears.

Answer:

forced convection

Explanation:

When a fan, pump or suction device is used to facilitate convection, the result is forced convection. Everyday examples of this can be seen with air conditioning, central heating, a car radiator using fluid, or a convection oven.

Answer:

Fluid viscosity, \(\mu = 2.57 * 10^{-3} kgm^{-1}s^{-1}\)

Explanation:

Container depth, D = 12 cm = 0.12 m

Tube length, l = 30 cm = 0.3 m

Specific Gravity, \(\rho\) = 0.95

Tube diameter, d = 2 mm = 0.002 m

Rate of flow, Q = 1.9 cm³/s = 1.9 * 10⁻⁶ m³/s

Calculate the velocity at point 2 ( check the diagram attached)

Rate of flow at section 2, \(Q = A_2 v_2\)

\(Area, A_2 = \pi d^{2} /4\\A_2 = \pi/4 * 0.002^2\\A_2 = 3.14159 * 10^{-6} m^2\)

\(v_{2} = Q/A_{2} \\v_{2} =\frac{1.9 * 10^{-6}}{3.14 * 10^{-6}} \\v_{2} = 0.605 m/s\)

Applying the Bernoulli (energy flow) equation between Point 1 and point 2 to calculate the head loss:

\(\frac{p_{1} }{\rho g} + \frac{v_{1}^2 }{2 g} + z_1 = \frac{p_{2} }{\rho g} + \frac{v_{2}^2 }{2 g} + z_2 + h_f\\ z_1 = L + l = 0.12 + 0.3\\z_1 = 0.42\\p_1 = p_{atm}\\v_1 = 0\\z_2 = 0\\\frac{p_{atm} }{\rho g} + \frac{0^2 }{2 g} + 0.42= \frac{p_{atm} }{\rho g} + \frac{0.605^2 }{2 *9.8} +0 + h_f\\h_f = 0.401 m\)

For laminar flow, the head loss is given by the formula:

\(h_f = \frac{128 Q \mu l}{\pi \rho g d^4} \\\\0.401 = \frac{128 * 1.9 * 10^{-6} * 0.3 \mu}{\pi *0.95* 9.8* 0.002^4}\\\\\\\mu = \frac{0.401 * \pi *0.95* 9.8* 0.002^4}{128 * 1.9 * 10^{-6} * 0.3} \\\\\mu = 2.57 * 10^{-3} kgm^{-1}s^{-1}\)

Answer:

0.00257 kg / m.s

Explanation:

Given:-

- The specific gravity of a liquid, S.G = 0.95

- The depth of fluid in free container, h = 12 cm

- The length of the vertical tube , L = 30 cm

- The diameter of the tube, D = 2 mm

- The flow-rate of the fluid out of the tube into atmosphere, Q = 1.9 cm^3 / s

Find:-

To determine the viscosity of a liquid

Solution:-

- We will consider the exit point of the fluid through the vertical tube of length ( L ), where the flow rate is measured to be Q = 1.9 cm^3 / s

- The exit velocity ( V2 ) is determined from the relation between flow rate ( Q ) and the velocity at that point.

                              \(Q = A*V_2\)

Where,

             A: The cross sectional area of the tube

- The cross sectional area of the tube ( A ) is expressed as:

                                \(A = \pi \frac{D^2}{4} \\\\A = \pi \frac{0.002^2}{4} \\\\A = 3.14159 * 10^-^6 m^2\)

- The velocity at the exit can be determined from the flow rate equation:

                              \(V_2 = \frac{Q}{A} \\\\V_2 = \frac{1.9*10^-^6}{3.14159*10^-^6} \\\\V_2 = 0.605 \frac{m}{s}\)

- We will apply the energy balance ( head ) between the points of top-surface ( free surface ) and the exit of the vertical tube.

                    \(\frac{P_1}{p*g} + \frac{V^2_1}{2*g} + z_t_o_p = \frac{P_2}{p*g} + \frac{V^2_2}{2*g} + z_d_a_t_u_m + h_L\)

- The free surface conditions apply at atmospheric pressure and still ( V1 = 0 ). Similarly, the exit of the fluid is also to atmospheric pressure. Where, z_top is the total change in elevation from free surface to exit of vertical tube.

- The major head losses in a circular pipe are accounted using Poiessel Law:

                           \(h_L = \frac{32*u*L*V}{S.G*p*g*D^2}\)

Where,

                  μ: The dynamic viscosity of fluid

                  L: the length of tube

                  V: the average velocity of fluid in tube

                  ρ: The density of water

- The average velocity of the fluid in the tube remains the same as the exit velocity ( V2 ) because the cross sectional area ( A ) of the tube remains constant throughout the tube. Hence, the velocity also remains constant.

- The energy balance becomes:

                      \(h + L = \frac{V_2^2}{2*g} + \frac{32*u*L*V_2}{S.G*p*g*D^2} \\\\0.42 = \frac{0.605^2}{2*9.81} + \frac{32*u*(0.3)*(0.605)}{0.95*998*9.81*0.002^2} \\\\u = 0.00257 \frac{kg}{m.s}\)

- Lets check the validity of the Laminar Flow assumption to calculate the major losses:

                     \(Re = \frac{S.G*p*V_2*D}{u} \\\\Re = \frac{0.95*998*0.605*0.002}{0.00257} \\\\Re = 446 < 2100\)( Laminar Flow )

Explanation:

The power factor of the circuit with R = 8 Ω and two capacitors with reactance -j2 Ω each is 0.788, indicating a lagging power factor.

To determine the power factor for the given circuit, we need to first calculate the impedance of the circuit.

The circuit has three impedance, R = 8 Ω, and two capacitors with reactance -j2 Ω.

To find the total impedance Z of the circuit, we need to add the impedance of the components in series.

The reactance of capacitors adds in series as if they were resistances in parallel, so we can calculate it using the formula:

1/Zc = 1/jwC = -j/(wC)

where w is the angular frequency (in radians/second) and

C is the capacitance (in farads).

Let's assume that the frequency of the AC source is 50 Hz, which corresponds to an angular frequency of w = 2*π*50 = 314.16 rad/s.

The impedance of the circuit can be calculated as follows:

Z = R + Zc1 + Zc2

Z = 8 - J/(wC) - J/(wC)

Z = 8 - J(1/(314.162*10⁻⁶) + 1/(314.162*10⁻⁶))

Z = 8 - J(3183.1 + 3183.1)

Z = 8 - J*6366.2

The magnitude of the impedance is |Z| = 6366.5 Ω, and the phase angle of the impedance is θ = -39.26 degrees.

The power factor of the circuit is given by the cosine of the phase angle, so:

PF = cos(θ)

PF = cos(-39.26)

PF = 0.788

Since the power factor is positive, we know that it is a lagging power factor.

Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Explanation:

Given that;

Weight of soil r = 118 lb/ft³

stress parameter C = 250 lb/ft²

φ total = 29°

depth Z = 12 ft

The shear strength on a horizontal plane at a depth of 12ft

ζ = C + δtanφ

where δ = normal stress

normal stress δ = r × z = 118 × 12 = 1416

so

ζ = C + δtanφ

ζ = 250 + 1416(tan29°)

ζ = 250 + 1416(tan29°)

ζ = 250 + 784.9016

ζ = 1034.9015 lb/ft²

Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²
