Question: A closed system of mass 10 kg undergoes a process during which there is energy transfer by work from the system of 0.147 kj/kg, an elevation decrease of 50 m, and an increase in velocity from 15 m/s to 30 m/s. The specific internal energy decreases by 5 kJ/kg and the acceleration due to gravity is constant at 9.7m/s2.
Part A: Determine the heat transfer for the process in kJ.
Please explain each step and equations used.
