FIRST LAW OF THERMODYNAMICS CONSERVATION OF ENERGY – OPEN SYSTEM A pump in a municipality's water supply system receives water from the filtration beds and pumps it up to the top of a water tower. The tower's height is 35 m, and the inlet piping to the pump is 2 m below the pump's intake. The water temperature is 20 °C, measured at both the inlet and discharge from the pump. The mass flow rate through the pump is 100 kg/s' the diameter of the inlet piping is 25 cm, and the diameter of the discharge piping is 15 cm. Assuming that there is no heat transfer and no change in internal energy of the water, determine the power required by the pump. Ans: -37.68 kW

Q1. A hydroelectric station has a cubic tank of height 50m above the earth. This cubic tank has an equal part of 35m. The maximum height of water in the tank is 25m for one day and the minimum height of water in the tunk is Sm for one day also. The efficiency of the station is 0.9. Find 1. The power that developed by the station. 2. The maximum power that developed by the station. 3. The maximum power that could be developed by the : 35m 25m S0m earth
kg). Q3. The steam at 215 bar and 500 °C is supplied to a steam turbine. It expands to 40 bar and 280 °c. It is then reheated to 490 °C and expands to 8 bar and 270 °C. The steam coming out from the second expansion of the turbine is further reheated to 490 °C and expands to condenser pressure of 0.07 bar. The steam entering into the condenser is dry saturated. Assuming the pressure losses in first heater of 1 bar and in second heater 0.5 bar, find (a) the thermal efficiency and power developed if the flow of steam is 10 kg/s (b) the isentropic efficiency of the expansion stages. Neglect the pump work. Mis-n-n (42.8 %, 1738 kW,78.5%,95.4 %, 87%) Q4. The steam nt 100
