Given the data of experimental test of a gear pumps as:
Pump speed = 1******rpm (* is your last digits of student ID).
Water flowrate =12.14(lit/min)
Suction pressure = -0.06 bar
Discharge pressure = 1.3 bar
Force of mechanical brake =1.35 N
Arm of mechanical brake =20 cm
Find:
a) Actual pump head
b) Water power
c) Mechanical power
d) Pump efficiency
