A 1-m3 rigid tank initially contains air at 150 KPa, 300 K. The tank is connected through a valve to a supply line at 300 KPa, 380 K. When the final pressure in the tank reaches 300 KPa the valve is closed. Due to heat transfer from the tank, the final tank temperature is measured at 320 K. Calculate: a) The mass of the air that has entered the tank, and b) The heat transfer from the tank. (Use Table for air enthalpy and internal energy property values)

Determine the reactions of simply supported beam to both a concentrated and uniform load. A beam with a span of 21 ft is simply supported at the left-hand end and fixed at the right-hand end.
What are the possible outcomes of this scenario?
A stationary gas turbine power plant operates on a simple ideal Brayton cycle with air as the working fluid. The air enters the compressor at 95 kPa and 290 K and the turbine at 760 kPa and 1100 K. Heat is transferred to the air at a rate of 35,00..
How often would the sample have to be taken - If the objective was to determine the average value of the material in the bunker, how could this be done by making one measurement?
During the process, the pressure and specific volume are related by pv = constant. For the refrigerant, determine the work and heat transfer per unit mass, each in KJ/kg.
