An isobaric nitrogen gas distribution tank has two inlets, A and B, and one outlet, C. Inlet A supplies 0.3 kgs¹ of very cold nitrogen gas at 0.5 MPa and -193.15°C (80K); inlet B supplies 0.8 kgs¹ of warmer nitrogen gas also at 0.5 MPa but at an unknown temperature. The nitrogen leaves the tank through outlet C at 0.5 MPa and a constant 15°C. There is a constant heat input of 3 kW into the tank. Determine the temperature of the nitrogen gas entering via inlet B, in °C. Assume steady-state, steady-flow conditions, and list any other appropriate assumptions.
