Question
During the early stages of designing a modern electric generating plant, you are in charge of the team of environmental engineers. The new plant is to be located on the ocean and will use ocean water for cooling. The plant will produce electrical power at the rate of 0.840 GW. Because the plant will have an efficiency of one-third (typical of most modern plants), heat will be released to the cooling water at the rate of 1.68 GW. If environmental codes require that only water with a temperature increase of 14°F or less can be returned to the ocean, estimate the flow rate of cooling water through the plant. kg/s
Explanation / Answer
increase in temperature,dT = 14 F
= 14*100/180 C
= 7.78 degrees celsius
now Apply,
Q = m*c*dT
dQ/dt = (dm/dt)*C*dT
==> dm/dt = (dQ/dt)/(C*dT)
= 1.68*10^9/(4186*7.78)
= 5.16*10^4 kg/s <<<<<<<<<<<-----------Answer
