(a) Use the following data to calculate the area of solar domestic hot water collector that would be needed to satisfy the family's requirement in hot water at 60oC if each of them uses on average 80 litres per day (5 people). (b) What is the total hot water energy used over a period of one year. Total solar energy received per day : 5 kWh/m2 Supply water temperature: 15°C Water average specific heat capacity : 4.2 kJ / (kg K) Solar collector average efficiency : 65% Note that: 1kWh = 3.6MJ

Heat Engine you are an engineering consultant who has been tasked with providing power to a remote village. After some initial evaluation it was determined that a simple four-device heat engine with water as the working fluid is the best option to produce electricity at the location. Natural gas and wood are abundantly available as a fuel source and 400 kW of power is needed. Design a heat engine to meet the stated requirements.
