d. Water is pumped through a 30mm diameter pipe from a bole hole to the surface. The pump submerged in water 10meters deep and is located at a depth of 60 meters below the ground. The water required to be pumped at a rate of 5 cubic meters per hour and travels through a 30mm pipe for the first 60meters and then through a 20mm pipe horizontally on the ground before exiting into a reservoir exposed to atmospheric pressure. Considering the losesa presumed in the first section as 10cm-lost per meter traveled and in the second section as 15cm lost per meter traveled. Calculate the following
a. The total head loss
b. The pressure, velocity and physical heads
c. The required pump head
d. The power requirement of the pump if it has an efficiency of 65%.
