Water creates pressure or resistance, at predictable rates, so we can calculate pump head as the differential pressure that a pump has to overcome in order to raise the water. Common units are feet of head and pounds per square inch. (A pump characteristic curve calculator might offer ...
The higher the horsepower, the more powerful the motor, in theory. We say in theory because to calculate the motor’s “Total HP,” we will need the service factor. Service Factor (SF) –The service factor is a multiplier by which we can determine a motor’s “Total HP.” The ...
All of the other things directly attached to the engine, like the water pump, oil pump, alternator, etc. Because so much energy is needed and because a car uses a 12-volt electrical system, hundreds of amps of electricity must flow into the starter motor. The starter solenoid is essentiall...
PROBLEM TO BE SOLVED: To provide an outboard motor in which 2-horsepower outboard motor with no backward traveling clutch gear of bar handle specification is changed to steering wheel remote control specification and which can be used in a wide use such as leisure boat and a rental boat.收藏...
This gives us the "per second" we need to calculate horsepower. Let's put this all together. We need to get to horsepower, which is 550 foot-pounds per second, using torque (pound-feet) and engine speed (RPM). If we divide the 550 foot-pounds by the 0.10472 radians per second (...
When I got my first car, I was so happy. It had black paint, a great motor, incredible horsepower (HP). But unfortunately, when I looked closer at the body paint, there were some weird smudges on it, which irritated the hell out of me. ...

A good introduction to how cars work, mainly aimed at mechanics. Section 2 covers engines in detail. American Horsepower by Mike Mueller. MotorBooks International, 2006. Great photos and detailed descriptions of some of the greatest car engines of the last 100 years. Legendary Car Engines by ...
A DC motor consumes 36 MJ of energy when connected to 230 V FOR 2.5 hours. a. Calculate how many kWh is the amount of energy mentioned above. b. The power taken by the motor from the mains. c. The current taken by the motor from the mains. How to convert square feet to square ...
How much horsepower are we talking about here? You can calculate how many foot-pounds of horsepower this engine produces using a common equation: The engine that makes 300 pound-feet of torque at 4,000 RPM produces [(300 x 4,000) / 5,252] 228 horsepower at 4,000 RPM. But where does...
