An engine draws water from a depth of 10 m with constant speed (at out

1.	An engine draws water from a depth of 10 m with constant speed (at outlet) 2 m/sec at the rate of10 kg per 10 s the power of the engine is (g = 9.8 m/s')?(A) 102 W(B) 50 W(C) 100 W(D) 98 W
Answer» Answer: Option (D) 98 W The power of the engine is 98 W Explanation: Depth h = 10 m Time taken in drawing WATER upto height of 10 m = 10/2 = 5 seconds In 5 seconds the mass of water drawn m = 5kg Total work done = MGH = 5 × 9.8 × 10 = 490 Joule Power is given by P = Work Done/Time = 490/5 = 98 W Hope this helps.

Answer»

Answer:

Option (D) 98 W

The power of the engine is 98 W

Explanation:

Depth h = 10 m

Time taken in drawing WATER upto height of 10 m = 10/2 = 5 seconds

In 5 seconds the mass of water drawn m = 5kg

Total work done = MGH

= 5 × 9.8 × 10

= 490 Joule

Power is given by

P = Work Done/Time

= 490/5

= 98 W

Hope this helps.
