(10-23)The shown four offices are to be heated by warm air heating system. The following data are given: The calculated heating loads for the offices are: Q=3,465 W, Q₂ = 2,755 w, Q, = 2,615 W and Q = 2,895 W. Inside design temperature is 20°C. Warm air temperature and velocity leaving the furnace are 55°C and 5 m/s, respectively. Density and specific heat of air are 1.15 kg/m³ and 1.005 kJ/kg-K, respectively. Calculate the followings: (a) Supply volumetric flow rate of air to each office.

Discuss briefly the different types of heat loads which have to be taken into account in order to estimate the total heat load of a large restaurant for summer air conditioning?

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
