1 In a steady flow apparatus, a fluid enters with a specific volume of 0.40m³/kg, a pressure of 550 kPa and a velocity of 20 m/s. The inlet port is 40 m above the floor and the outlet port is at the floor level. The fluid exits with a specific volume of 0.82m2/kg, a pressure of 100 kPa and a velocity of 280 m/s. The apparatus produces 140 kJ of work per kg of fluid and a 12 kJ/kg of heat loss occurs between the inlet and outlet ports. Determine the amount of change in internal energy in the apparatus. Is the internal energy increases or decreases?

Q1: If a calorimeter is not assumed to be adiabatic, how would one calculate the heat transfer? Guide Questions: What are the parameters to be considered and the equations to be used? What law of thermodynamics does this transfer of heat to the surroundings touch? Is an adiabatic system automatically considered as a closed system? Please help me understand by also attaching a reference/book/journal article. This would help me in my essay. Thank you.
