P.4.10
Oil of viscosity 10 mNs/m? and specific gravity 0.90, flows through 60 m of 100
mm diameter pipe and the pressure drop is 13.8 kN/m?. What will be the pressure drop
for a second oil of viscosity 30 mNs/m2 and specific gravity 0.95 flowing at the same
rate through the pipe? Assume the pipe wall to be smooth.

2. Suppose the pump of Fig. P14-23 is operating at efficient condition. The pipe diameter after the pump is
"X" cm and pipe diameter before the pump is "Y" diameter. The friction losses along the pipe are negligible
(no need to use Darcy Equation). But there are minor losses in the system. They are as follows; the sharp
inlet is 0.50 m of water, each valve has a loss of 2.4 m of water, and each of the three elbows has a loss of
0.90 m of water. The contraction at the exit reduces the diameter by a factor of 0.60 (60% of the pipe
diameter(after the pump)), and the loss of the contraction is 0.15 m of water. The volume flow rate is "K"
Lpm. Density= 990kg/m. dynamic viscosity=1.002 x103 kg/m-s. Z1-Z2="L". The kinetic energy correction
factor is 1. Determine (a) Required Head, (b) Required pump power (water Hp), (c) Reynolds number at
the exit.

- Q.5 A pump circulates water through a closed pipe network connecting a water heater and a heating coil (heat exchanger) in a room. The total length of the pipe is 28 m and the diameter is 32 mm. There are six 90°-elbows and a globe valve in the network. The head loss through the water heater and the heating coil are 1.6 m and 1.2 m respectively. The water flow rate is 0.88 Ls!.
