Problem 1: A sealed rigid tank of 1 m3 capacity contains 1.2 kg of water at 1 bar and 99.63 °C. To this tank we add heat until the pressure increases to 3 bar. a) What is the temperature at the end of the heating? b) Calculate the amount of vapor before and after the heating. c) Calculate the amount of heat added.
Use the total energy of charge distribution to calculate the total electrostatic energy of a uranium 235 nucleus. It has 92 protons and a radius of about 7.0 femtometers?
A vapor rate of 2500 kg/h is required and the vaporizer will operate at 6 bara. Size the vessel to restrict the carryover of liquid droplets. The liquid hold-up time need not be considered, as the liquid level will be a function of the thermal des..
