Question

A pumping machine pumps water at rate of 60 cc per sec at pressure of 1.5 atm. What is the power delivered by the machine?

Answer 1

Pressure = 1.5 atm

= 1.5x10 raise to power 1.5  Pa

Volume

V = 60 cc

= 60x10 raise to power –6 m raise to power 3

Time:  

T=1 s  

Power:  

P= w/t  

= pv/t  

= (1.5x10 raise to power 5) (60x10 raise to power minus 6)/1  

You can solve this to get the answer
