You have a 60 gallon hot water tank at home that is heated at 60oC. Hot water is taken from the tank and mixed with the required amount of water at 10oC to supply a hot shower using 8 L/s of water that is at 45oC. How big of a heating element is required in the tank to keep its temperature constant at 60oC. Assume that 5% of the heat is lost to the environment

Hot water is required as utility in a certain bioprocess. 10,000 g/h water at 28oC enters an open heating tank, where heated up to 80oC. 11% of this water is lost from the system via evaporation. a. Construct the mass balance in order to calculate how much water is evaporated and how much water is leaving the tank. b. What must be the rate of heat input to the system at steady-state? h (liquid water at 28oC) = 117.3 kJ/kg...

Thermodynamics deals with the macroscopic properties of materials. Scientists can make quantitative predictions about these macroscopic properties by thinking on a microscopic scale. Kinetic theory and statistical mechanics provide a way to relate molecular models to thermodynamics. Predicting the heat capacities of gases at a constant volume from the number of degrees of freedom of a gas molecule is one example of the predictive power of molecular models. The molar specific heat Cv of a gas at a constant volume...
