Pedas hot water spring is located 15 km from Seremban town. The government has decided to build geothermal power plant using hot water from Pedas hot water spring. A geothermal power plant uses geothermal water at 150°C at a rate 210 kg/s as the heat source and produces 8000kW of net power. The geothermal water leaves the plant at 90°C. If the environment temperature is around 25°C. Determine:
a. The actual rate of heat input to this power plant.
b. The actual thermal efficiency and the maximum possible thermal efficiency of this power plant.
c. The actual rate of heat rejection from this power plant.
d The power output if the geothermal water leaves the plant at 40°C, and maintain it thermal efficiency.
