**Pump input or brake power** (BkW) is the actual horsepower delivered to the pump shaft. Pump output or hydraulic or pump power (PkW) is the liquid horsepower delivered by the pump.ekW = electrical power (electrical kW) **bkW = engine power (brake kW)**Bkw (**brake kilowatts**) is the power actually required to drive a piece of equipment. In this context, kw would be the power rating of the chosen driver. (Oftentimes the next standard size larger than the bkw.)

## How is BkW of pump calculated?

Pump power P_{(}_{kW}_{)} in kilowatts is equal to the product of the rate of flow q_{(}_{m}^{3}_{/}_{hr}_{)} in cubic meter per hour, fluid density ρ_{(}_{kg}_{/}_{m}^{3}_{)} in kilogram per cubic meter, gravity g in m^{2}/s, pump differential h_{(}_{m}_{)} head in meter and the differential pressure p_{(}_{Pa}_{)} in Pascal or N/m^{2} divided by 36,00,000.

## What does brake horse power mean?

Brake horsepower is **the horsepower of an engine measured by the degree of resistance offered by a brake, that represents the useful power that the machine can develop**. For an electric motor, brake horsepower is the mechanical horsepower available at the shaft at specified rpm and full load current.

## How many watts is 1kwh?

One kilowatt is equal to **1,000 watts**, so to figure out the kWh per day that your refrigerator uses, you simply need to divide the watt-hours per day (7,200) by 1,000 for a total of 7.2 kWh per day.

## What is 1kwh?

The kilowatt-hour (symbolized kWh) is **a unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour (1 h) of time**. The kilowatt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications.

## How do I calculate flow rate?

To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is **total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL)**, which equals the IV flow rate in gtts/min.

## Is BHP higher than HP?

While hp does not take into account frictional losses in power from an engine, brake horsepower does — meaning **hp is always higher than bhp**. The difference between the two is small on a 1:1 basis. 1hp is the equivalent to just under 0.99bhp, though scaled up you’ll notice differences.

## Is higher BHP better?

For instance, the engine power of an Aston Martin DB9 can be expressed as 540 bhp or 403 kW … the bhp figure sounds much more impressive, but both represent the same amount of power. So, for hp, bhp, ps or kw **the bigger the number, the more the power and so the higher the top speed**.

## What is a good brake horsepower?

While the average car engine requires an approximate BHP (brake horsepower) of 120, larger SUVs may require 200bhp and smaller vehicles may only require 70bhp. Overall, **an appropriate BHP will depend on the weight of your car**.

## How do I calculate kWh per hour?

A kilowatt-hour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. Thus, to convert watts to kilowatt-hours, **multiply the power in watts by the number of hours, then divide by 1,000**.

## How do I calculate kWh?

To get the number of kWh, you just **multiply the number of kW by the number of hours the appliance is used for**. For example, a device rated at 1500 W that’s on for 2.5 hours: 1500 ÷ 1000 = 1.5. That’s 1.5 kW.

## How many watts is a refrigerator?

The average home refrigerator uses **350-780 watts**. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it.
