#Section 4: Fundamentals of Biological Engineering

Water at 25°C enters an open heating tank at a rate of 10 kg h^-1. Liquid water leaves the tank at 88°C at a rate of 9 kg h^-1; 1 kg h^-1 water vapour is lost from the system through evaporation. At steady state, what is the rate of heat input to the system?

h (liquid water at 25°C = 104.8 kJ kg^-1) 

h (liquid water at 88°C = 368.5 kJ kg^-1) 

h (saturated steam at 88°C = 2656.9 kJ kg^-1)
