Water in a piston–cylinder assembly, initially at a temperature of 99.638c and a quality of 65%, is heated at constant pressure to a temperature of 2008c. if the work during the process is 1300 kj, determine (a) the mass of water, in kg, and (b) the heat transfer, in kj. changes in kinetic and potential energy are negligible.
