I need very QUICK answers, PLEASE. A solar collector meets the hot water needs of a family for 7 months, excluding 5 months of the winter season. This collector provides hot water at an average temperature of 55°C and an average cold water temperature of 16°C. The family uses an average of 14 tons of hot water per month from the solar collector, and in winter, hot water is provided by an electric heater. Since the unit price of electricity is 0.85 TL/kWh and the efficiency of the electric heater is 91%, calculate the annual electricity and money savings provided by the solar collector to the family. (Specific heat of water at room temperature=4.18kJ/kg*C)
3) When a person enters his house, which is completely closed in summer, he sees that the temperature is 34°C. After turning on the air conditioner, the temperature of the house becomes 22 °C within 15 minutes. Since the efficiency coefficient of the air conditioning system is 3.2, a) the electrical power drawn by the system, b) heat dissipated to the environment, and c) Assuming that it works 8 hours a day and the electricity price is 0.6 TL per kWh, find its cost for 4 months. Assume that the entire mass inside the house is equivalent to 1000 kg of air. For air, take Cv = 0.73 kJ/kgK, Cp= 1.0051 kJ/kgK.
