Consider calculating the amount of natural gas required to heat water in a heater. A family in Oklahoma uses 84 gallons of hot wat of 60°F to 135°F. Assume the efficiency of the heater is 82%. (The density of water is 1,000 kg/m³. Note that 1 cubic meter is 264 rounded intermediate values in your calculations-including answers submitted in WebAssign.) What is the mass of hot water consumed by the family per day (in kg/day)?

Question

and finally find the volume rate in ft3/day

Consider calculating the amount of natural gas required to heat water in a heater. A family in Oklahoma uses 84 gallons of hot water per day. The water is heated from a line temperature of 60°F to 135°F. Assume the efficiency of the heater is 82%. (The density of water is 1,000 kg/m³. Note that 1 cubic meter is 264 gallons. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) What is the mass of hot water consumed by the family per day (in kg/day)? kg/day What is the specific heat of water (in J/(kg K))? J/(kg. K) What is the temperature rise in K? K How much power is required to heat the water in the heater each day (in W)? W How many Btu/h are equal to 1 W? Btu/h Express the power required in Btu/h. Btu/h What is the heating value (at 60°F) of natural gas in Oklahoma (in Btu/ft³)? Btu/ft³ Determine the volume of natural gas required to heat the water in the heater in ft3 per hour and ft³ per day. volume rate in ft³/h ft³/h
