Also if you want to calculate high powers, for example, 2^1000, it may be quicker to calculate 2^100, then take that result and raise that to the power 10 The calculation would go on forever, so we have to stop somewhere. By multiplying air velocity by the cross section area of a duct, you can determine the air volume. For example, a company might fund a capital project that loses money for five straight years and makes a huge profit on the sixth year. The ideal hydraulic power to drive a pump depends on the mass flow rate, the liquid density, and the differential height. We used the ProMax calculated polytropic and isentropic efficiencies, compression ratio ( P 2 /P 1 ), heat capacity ratio ( k ) and polytropic exponent ( n ) to calculate head, power. 5, OR=exp(0.

Flashcards. , thousands of watts) it’s best to either convert it to watts (by multiplying by 1,000) or keep it in kilowatts make sure your voltage is in kilovolts (kV = volts ÷ 1,000). Check out our pond kits, fish pond liners, pond pumps and other products. Overall, taking into account the RHI payments and bill savings, a renewable heating scheme will provide a return on investment of approximately 15% per annum. You’ll need 1. Numerical Example. Calculate the pump power, in brake horsepower or bhp, using the following formula: bhp = (Q X P) / (1714 X ME) 1714 is a conversion factor to For example, if you're designing a pump to recirculate a spa, you need to know the speed at which the pump must run, given the size of the pump's cylinder. Pump Efficiencies of 11 dB/mW achieved at 980 nm. The vapor is expanded in the turbine, thus producing work which may be converted to electricity. For example, if you want the number 100000000 as a scientific. An example of this is the air pressure in an automobile tire, which might be said to be "220 kPa (32 psi)", but is actually 220 kPa (32 psi) above atmospheric pressure. Units that run exclusively DC power will only pump off battery power. Best Power to Weight Ratio 5. Electric Motor Absorbed Power Estimation Very often one needs to know the power absorbed by say, a pump or a carrier or fan or some other equipment driven by an electric motor. Efficiency is the ratio between the input power and output power. The shaft power - the power required transferred from the motor to the shaft of the pump - depends on the efficiency of the pump and can be calculated as Ps =Ph / where P s = shaft power (kW) = pump efficiency Default Value 30 1000 9.
