Question 1)Water vapor enters with a continuous flow adiabatic turbine, 3MPa press, 400 oC temperature and 90 m3 / min volumetric flow rate. Some of the steam comes out of the turbine at a pressure of 0.5 MPa and a temperature of 200 oC. The remainder is abandoned in the 5 kPa pressure and 90% composition registration system. Calculate the mass flow rate at the outlet no. 2 by neglecting the kinetic and potential energies according to the total power generated in the turbine 5 MW.

Question 2)2.5 kW of solar energy comes upon renovation of a house. 25% of this incoming energy is lost to the environment, and the remaining energy is used to increase the temperature of the water passing through the solar panel from 30 oC to 60 oC. Determine how many liters of water pass through the solar panel in order to ensure the increase in water temperature under continuous operating conditions. Use the density of the water as 1000 kg / m3. Also, neglect the pressure loss, kinetic and potential energy changes in the water flowing through the solar panel.
