Consider incompressible flow in a circular channel. Derive general expressions for Reynolds number in terms of (a) volume flow r

Georgia [21]

Answer:

a) $Re = \frac{4\cdot \rho \cdot Q}{\pi\cdot \mu\cdot D}$ , b) $Re = \frac{4\cdot \dot m}{\pi\cdot \mu\cdot D}$ , c) 1600

Explanation:

a) The Reynolds Number is modelled after the following formula:

$Re = \frac{\rho \cdot v \cdot D}{\mu}$

Where:

$\rho$ - Fluid density.

$\mu$ - Dynamics viscosity.

$D$ - Diameter of the tube.

$v$ - Fluid speed.

The formula can be expanded as follows:

$Re = \frac{\rho \cdot \frac{4Q}{\pi\cdot D^{2}}\cdot D }{\mu}$

$Re = \frac{4\cdot \rho \cdot Q}{\pi\cdot \mu\cdot D}$

b) The Reynolds Number has this alternative form:

$Re = \frac{4\cdot \dot m}{\pi\cdot \mu\cdot D}$

c) Since the diameter is the same than original tube, the Reynolds number is 1600.

Describe and compare the characteristics of (a) proportional control, (b) proportional plus integral control, (c) proportional p

stira [4]

Answer:

The answer is below

Explanation:

1. Proportional Control is a form of control engineering in which an output is directly proportional to the error signal.

Characteristics of proportional control are:

* It is utilized when the deviation between the input and output is small

* It is also utilized when the deviation is not sudden.

* It reduces steady-state error

* It speeds up the response of the overdamped system

2. Proportional plus Integral Control is a form of control engineering in which a collective proportion and integral control of the output is equivalent to the combined proportion and integral of the error signal.

Characteristics of proportional plus integral control are:

* it can revert the controlled variable to the original set point

* It decreases steady-state error

* It quickens up the reaction of the overdamped system

3. Proportional plus integral plus derivative control is mostly applicable in operating the process elements such as temperature, pressure, speed, etc. It is recommended for industrial use.

Characteristics of Proportional plus integral plus derivative control are:

* It enhances the temporary reaction of the system.

* It also lessens steady-state error

* It accelerates the response of the overdamped system

An electric winch operates on 140 volts [V] and draws 6 amperes [A] of current. The winch has an efficiency of 64%. The winch

Elis [28]

Answer:

Explanation:

efficiency = (energy output / energy input)

energy input = ivt where i is current = 6 A, v is volts = 140 and t time = 11 seconds

energy input = 6 × 140 × 11 = 9240 J

energy output = 0.64 × 9240 = 5913.6 J

510 pound-force = 2268.593 N

at height h, potential energy = mgh = 5913.6 J

2268.593 × h = 5913.6

h = 5913.6 / ( 2268.593) = 2.61 m
