Required information Problem 04.122 - Energy balance for a passive solar house A passive solar house that is losing heat to the outdoors at an average rate of 50,000 kJ/h is maintained at 22°C at all times during a winter night for 10 h. The house is to be heated by 50 glass containers each containing 20 L of water that is heated to 80°C during the day by absorbing solar energy. A thermostat-controlled 19.00-kW backup electric resistance heater turns on whenever necessary to keep the house at 22°C. The density and specific heat of water at room temperature are p= 1 kg/L and c=4.18 kJ/kg. °C. 22°C Water 80°C Pump Problem 04.122.b - On-time for the electric heating system How long would the electric heater run that night if the house incorporated no solar heating? (Round the final answer to three decimal places.) The electric heater would run for h.

1. .Mexico's metro requires the implementation of an air conditioning system for each of its cars. On the hottest days the air inside the car can reach 45°C. A temperature of 25°C is expected to be achieved to keep passengers satisfied. A car measures 17 m x 2.5 x 2. In order to make the decision on the air conditioning system to install, the engineering director has asked to calculate: A. Amount of energy to be removed from the car when the air is at 45°C and the car is empty. B. Amount of energy to withdraw when the car is full (approx. 130 people with a volume of 0.06 m3/person). Each person releases 30 kJ while in the car. C. Power of a system that removes the estimated energy A and B in less than 1 minute.

Prepare a report on the heating systems available in your area for residential buildings. Discuss the advantages and disadvantages of each system and compare their initial and operating costs.

Pls. Answer thank you! A logging firm in Isabella operates a Diesel Electric Plant to supply its electric energy requirements. During a 2 hour period, the plant consumed 250 gallons of fuel at 80°F and produced 2900 kW-hrs. Industrial fuel is used at 30°API and was purchased at P30/li at 60°F. Determine the overall thermal efficiency in percent of the plant.
