5m3 of a liquid whose density is 1.8 g / is going to be pumped
from the floor level to a height of 12 m., If it is pumped in 45
min, what would be the pumping flow?
Select one:
to. 1211.11 l / m
b. 150.13 l / min
c. 160.13 l / min
d. 111.11 l / min
Homework Answers
Ans.Total volume of liquid(V)=5m3 =5×1000= 5000 litres.(1 m3 = 1000 litres)
Time taken in pumping the liquid(t) = 45 minutes
Volume flow rate or discharge (Q)= volume/time
Q= V/t = 5000/45= 111.11 l/min. Ans.( d)
Note. All given options are in l/min. So it is considered that volume flow rate is asked.

A liquid chemical is pumped from a storage tank open to the atmosphere, into a reactor with pressure of 2.0 atm gauge above the liquid level. The liquid density is 1200 kg/m3 and viscosity is 1.45 cP. The required volumetric flow rate is 1.25 x 103 m/s. The pipeline is 100 m long in total, made of commercial steel pipe, 2 in. size and Schedule 40. The gate valve is wide open. 10 m Reactor Calculate: (a) The discharge velocity...

Q2. 50 marks Water at 20°C is pumped at 5.7 m3 min-1 from the lower to the upper reservoir, as in Fig. 2. The free surface of the upper reservoir is at height Z2 = 46 m, and of the lower reservoir at 21 = 15 m. The pipe diameter before and after the pump is D= 15 cm. Pipe friction losses are approximated by h = 27v2/(29), where V is the average velocity in the pipe. The gravitational acceleration...

Oil (density = 910Kg/m3 and viscosity 3.1 x10-3 Pa-s) is pumped from an open tank to a pressurized tank held at 400KPa gauge. The oil is pumped from an inlet at the side of the open tank through a line of commercial steel pipe (inside diameter 0.8m) at a rate of 5x10-3 m3/s. The length of the straight pipe is 150 m, and the pipe contains 4 (90-degree) elbows and two globe valve half open. The level of the liquid...
