In a mixing chamber hot water enters at a temperature of 80 °C with a flowrate of 0.5 kg/s. From another entry, cold water enters the chamber at 20 °C. The desired temperature afte...

An adiabatic rigid and impermeable tank of volume 10 m³ contains air at 800 kPa and 70 °C. The air is allowed to leave the tank until the pressure is one-fourth of its original val...

Two kg of a gas is compressed in a process. Pressure (P) and mass specific volume (v) of the gas during the process follows: Pv^1.2 = constant. The temperature of the gas before an...

A rigid spherical solid ball at 1000 °C is cooled slowly to 200 °C in a surrounding air at 25 °C. The density, specific heat capacity, and diameter of the ball are 8000 kg/m³, 500...
