Aproposed ocean thermal-energy conversion (otec) system is a heat engine that would operate between warm water (16°c) at the ocean's surface and cooler water (6°c) 1,300 m below the surface. what is the maximum possible efficiency of the system? enter your answer accurate to two decimal places.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
