Consider a thermal insulated closed rigid tank which is divided into two parts A and B by a partition. Initially, Part A of the tank contains 10kg of an ideal gas at 60 deg C . Part B of the tank contains 22kg of the same ideal gas at 110 deg C. Then the partition is removed and the gas from both the parts of the tank is allowed to mix. After a certain period of time, the gas inside the tank reaches an equilibrium state. Determine
1) final equilibrium temperature of the gas,
2) total change in enthalpy of the gas (of amount 22kg + 10kg), by considering both the parts as one system. Consider Cp = 1.007kJ/(kg*K) for the gas.
