Question 10 (1 point) Consider a 10 hp motor running steadily and operating at electric input power = 7411 W, efficiency = 90.6%, and rotor speed = 1764 rpm. Wel 400 W The heat dissipation rate by the motor is closest to which of the following values? 500 W 600 W 700 W 800 W Q 900 W Vsh
Consider steadily running natural-gas furnace. exhaust air intake ventor burner fuel indoor air fan/motor supply air AAAA heat exchanger return air The natural gas flow rate to the burner is 2.29 m³/hr. The heat content of natural- gas is approximately 38 MJ/m³. The steady heat output rate of the furnace is 18.9 kW.
The natural gas flow rate to the burner is 2.29 m³/hr. The heat content of natural- gas is approximately 38 MJ/m³. The steady heat output rate of the furnace is 18.9 kW. Estimate the heating efficiency (%) of the furnace. Round your answer to one decimal place (e.g. 65.2) Your Answer: Answer
Question 10 (1 point) Consider a 10 hp motor running steadily and operating at electric input power = 7411 W, efficiency
