In the first case, two pipes are connected to a tank containing liquid water at 45kg and 45℃. Liquid water at a temperature of 45 ℃ flows from one of the pipes into the tank with a flow rate of 270 kg/h. From the other pipe, the liquid is discharged at the same flow rate as the entering liquid. With the help of a mixer, the water in the tank is mixed and the temperature in the tank is kept uniform. This mixer transfers 0.6 kW of power to the water in the tank. In addition, with the help of a cooling system immersed in liquid water, 7.6 kW of energy is drawn from the liquid. Find and plot the equation of the time variation of the water in the tank when the pressure is the same at the inlet and outlet of the tank and the water in the tank is considered incompressible. Note: The changes in potential and kinetic energies are neglected. Hint: Einlet-Eexit= dEsystem/dt
