Water enters an ice machine at 55F and leaves as ice at 25F. If the COP of the ice machine is 3.7 during this operation, determi

boyakko [2]

Answer:

The required power is $P_i = 0.2692 \ hp$

Explanation:

From the question we are told that

The temperature of the water entering ice machine is $T_1 = 55 ^o F$

The temperature of the water leaving is $T_2 = 25 ^oF$

The COP of the ice machine is $COP= 3.7$

The production rate of an ice $\r m = 15.0 \ lbm /hr$

The energy that needs to removed from each lbm of water at 55 F is $E = 169 Btu$

Generally the cooling load of the ice machine is mathematically represented as

$\r Q_L = \r m * E$

$\r Q_L =15 * 169$

=> $\r Q_L = 2535 \ Btu/h$

Generally the COP of the ice machine is mathematically represented as

$COP = \frac{\r Q_L}{P_i}$

Here $P_i$ is the net power input needed to successfully run the ice machine

$3.7 = \frac{2535}{P_i}$

=> $P_i = 685 \ Btu/h$

Converting to horsepower

$P_i = \frac{685}{2545}$

=> $P_i = 0.2692 \ hp$

A fluid is flowing with an average speed of 1.5 m/s through a tube that has a radius of 2.0 mm and is 18 cm long. The drop in pr

Ymorist [56]

Answer:

μ = 0.038 Pa.s

Explanation:

Given that

V= 1.5 m/s

r= 2 mm

L = 18 cm

If we assume that flow inside the tube is laminar ,then the pressure drop ΔP given as

$\Delta P=\dfrac{32\mu LV^2}{d^2}$

$\mu = \dfrac{\Delta P D^2}{LV^2}$

$\mu = \dfrac{967\times 0.004^2}{0.18\times 1.5^2}\ Pa.s$

μ = 0.038 Pa.s

The viscosity of the fluid = 0.038 Pa.s
