A) 9W
B) 6W
C) 9KW
D) None of these.
Correct Answer: A
Solution :
As, we know that power = F,V, where F = force imported by the machine, V = velocity of the liquid. \[P=\rho .A.V,\] where P = pressure and A = effective area \[=P\frac{d\upsilon }{dt}\] \[=\left( \frac{3}{2}\times {{10}^{5}} \right)\,\,(60\times {{10}^{-6}})=9W.\] \[(\because \,\,\,1\,atm={{10}^{5}}N{{m}^{-2}})\]
