Agarage (24 ft x 24 ft x 10 ft) is illuminated by six 60-w incandescent bulbs. (a watt (w) is a joule/second) it is estimated that 90% of the energy to an incandescent bulb is dissipated as heat. if the bulbs are on for 10 hours a day, how much would the temperature in the garage increase in that 10 hour period because of the light bulbs (assuming no other energy source and no energy losses through the walls of the garage). solve this problem in the excel worksheet showing all specified information and calculated information, clearly labeled with units. useful information:

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
