6. A Compressor of a compressed air system displaces air at 25 cubic meters per minute when the
intake pressure is 101.4 kPa. Compute the time required to pump up a 9 cubic meter receiver
from 550 kPa to 828 kPa if the average volumetric efficiency of the compressor is 70%
A large container filled with water and uncovered for use in fighting fires in an ethylene production plant. Water from this tank is pumped into the nozzle when needed use. This fire suppression system is designed to be able to transmit 1890 L/min of water at a pressure of 15 bar (relative pressure). If we ignore the difference in height between the water level in the tank and pump, there is no change in diameter of pipe and nozzle, pump efficiency is 70%. Ask how much work (hp) is required to the pump to achieve the desired pressure and flow would like?
Q1) Oil of specific gravity s.g = 0.8 is drawn into the pump, the pressure at A is -20 kpa and at B is
100 kpa. Calculate the power input of the pump if the discharge at B is 0.07 m'/s and the pipe
diameter is 80 mm and h = 2.5 m as shown in Fig.1. Neglect friction losses. Take the efficiency of
the pump 0.85
