How to calculate the brake horsepower of a fan?
Brake Horse Power – BHP Brake horse power – the actual power a fan requires because no fan is 100% efficient. BHP can be expressed as PBHP = q dpinWG / μ 6356 (2)
What is the heat loss from a 10 kW motor?
The heat loss from an electric motor supplied with 10 kW can with the heat loss 150 watts/kW from the table above be calculated as. (10 kW) (150 watts/kW) = 1500 watts.
How to calculate the horsepower of an air horse?
Air Horse Power – AHP Assuming 100% efficiency AHP is the power required to move a given air volume against a given pressure. AHP can be expressed as PAHP = q dpinWG SG / 6356 (1)
Where does heat loss from a motor occur?
motor and driven device in the room – all energy to the motor is at the end transferred to the room (heat loss from the motor and frictional energy from the driven device) motor in the room and device outside the room – only heat loss from the motor is transferred to the room – frictional energy from the driven device is lost outside the room
What should I do if my Yamaha buzzer overheats?
Boat is normally in river water with little operation in salt water…always run boat in river after salt water. Several dealer mechanics have tried correcting. Mechanic says engine is not overheating because he can touch both heads with hands. Approximately 550 hours total on engine.
How much heat does a 300 horsepower engine generate?
Based on these numbers, a 300 horsepower engine would generate about 750,000 BTUs of heat energy per hour at full throttle. A 400 horsepower engine would burn over a million BTUs per hour with the pedal to the metal. As the power level goes up, so does the waste heat produced by the motor.
The heat loss from an electric motor supplied with 10 kW can with the heat loss 150 watts/kW from the table above be calculated as. (10 kW) (150 watts/kW) = 1500 watts.
How does increasing horsepower affect the cooling system?
This leads us to the important part of this article, which is this: When you modify an engine to make more horsepower, you also increase the heat load on the cooling system. For every 100 horsepower increase in power output, the engine burns another 250,000 BTUs – and nearly a third of this is dumped into the cooling system.
