Question

pumping machine pumps water at the rate of 60 CC per second at a pressure of 1.5 atm power delivered by machine is..

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

Answer 2

Pressure = 1.5 atm

Volume= 60 × 10 ^-6 m^3

Power =p× v/t

And t= 1

Put all values .

You will get 9 watts as answer
