Actual horsepower requirements are 10 to 15 higher than this theoretical value because of friction, power transmission, and drive losses. For example, horsepower requirements for a bucket elevator with 1,600 buh of paddy and a lift of 10.7 m loaded on the up side would be 1,600 buh 545 kgminute Therefore the next larger standard size ...
Power is consumed by a pump, fan or compressor in order to move and increase the pressure of a fluid. The power requirement of the pump depends on a number of factors including the pump and motor efficiency, the differential pressure and the fluid density, viscosity and flow rate. This article provides relationships to determine the required pump power.

3.4 Horsepower Requirements. In rotary drilling, the engines that supply power are rated on output horsepower, sometimes called brake horsepower. Fluid pumps that receive power are rated on the basis of input horsepower. For this reason, a 1,600-hp pump classification means that the horsepower fed into the pump should not exceed 1,600.
Oct 28, 2015 Since this craft has 4 rotors , each rotor would need to produce at least 14 of the thrust or 90Kg 4 22.5Kg . Using our formula we can calculate power needed for each rotor Thus the total power required is estimated at 165.35W4 661.4 W , which is quite manageable for a trained cyclist.

Main principles of pumps selection. Selection of the pumping equipment is a crucial point that determines both process parameters and in-use performance of the unit under development. During selection of the type of pump three groups of criteria can be distinguished 1 Process and design requirements.
Aug 24, 2012 To use the chart, find the point where 2 hp and 151 ratio intersect. In this case, that indicates a size 726 gearbox. According to one manufacturers product-number system, size 726 defines a gearbox that has a 2.62 center distance. Such charts also work in reverse, to let engineers confirm the torque or speed of a given gearbox size.

In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel where s is the distance traveled. However, the objects speed, v, is just s divided by t, so the equation breaks down to.
