At a power station, heat is removed from the heat exchanger by cooling water at `6.7xx10^9` J per minute. The cooling water enters at `6.0^o C` and leaves at `14.0^oC`. [ Take the specific heat capacity of water 4200 J/K`g^oC`]
Which of the following is the rate of water flow?
A. |
`(6.7xx10^9xx60)/(4200xx8)` kg`s^(-1)` |
B. |
`(6.7xx10^9)/(4200xx8xx60)` kg`s^(-1)` |
![]() |
C. |
`(4200xx8)/(6.7xx10^9xx60)` kg`s^(-1)` |
D. |
`(4200xx8xx60)/(6.7xx10^9)` kg`s^(-1)` |
