Hi,
I am preparing for GATE(Chemical). I need the answer of this question part 2 (question 54) as I am not able to find the mistake in my logic.
I have applied the logic here as:
Initial energy stored in the system = energy stored in 1st tank when valve is closed + energy stored in 2nd tank when valve is closed
= (6000*10*6)+(2000*10*2) = 400,000 J
When height in both tanks reaches 4 m, flow stops.
Thus, final energy stored in the system = (4000*10*4)+(4000*10*4)=320,000 J
Thus, energy loss= 400,000-320,000=80,000 J
The answer for this question is 40,000 J while, mine as shown above is coming as 80,000 J.
Please advice where I am doing wrong.
