Cell 'A' with O.P. = 10 atm and T.P. = 5 atm. is contact with cell 'B' having O.P. = 15 atm. and T.P. = 12 atm. The flow of water will be

A. From A to B

B. Equal flow

C. From B and A

D. No flow

Answer: Option C

Solution(By Examveda Team)

Cell A has O.P. = 10 atm. And T.P. = 5 atm. DPD = O.P. - T.P. = 10 - 5 = 5 atm.
Cell B has O.P. = 15 atm. And T.P. = 12 atm. DPD = 15 - 12 = 3 atm.
The water flow from low to high pressure, as the DPD of cell B, is 3 and the DPD of cell A is 5, therefore water will flow from cell B to A.
