c (water) = 4190 j/kg•K density of water = 1000 kg/m^3
In Wakanda, at the Vibranium Institute of Energy Research, the sister of the Black Panther, Shuri has found a way to generate energy from the gradient in temperature of Lake Malawi. At some large depth the temperature of the water is 7.2 degrees C while at the surface it is 26.8 degrees C.
(a) The maximum theoretical efficiency of the research power plant is?
(b) It is hoped that the power plant can produce power equal to 217 kW. The cold water must absorb heat at what rate for this to happen? Assume the maximum theoretical efficiency.
(c) Water at 11 degrees C leaves the power plant having once been colder upon entrance. What must be the cold water flow rate through the plant? Express answer in kg/h and in L/h. please note: the cold water that enters the plant leaves, as said above, at 11 degrees C
