Un tanque rigido contiene 1.2m cubicos de argon a -100 °C y a una MPa . El calor se tranfiere a ahora al argon hasta que la temperatura en el tanque se eleva a cero grado utilizando tablas generalizada determine (a ) la masa del argon en el tanque , (b) la presion final (c) la tranferencia de calor.)

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
