The cost of using a well water pump can be calculated using the formula: Cost = Power (watts) x Time (hours) x Energy Price ($/kWh)/1000. Assuming an energy price of $0.12/kWh and a power consumption of 1000 watts, the costs of using a well water pump can be calculated as follows: Daily cost: 1000 x 24 x 0.12/1000 = $2.88. The model 85 was a RWD 85 kWh battery with 278 kW (373 hp) and 441 N⋅m (325 lbf⋅ft). The Performance variant (P85) offered a three-phase, four-pole AC induction 310 kW (416 hp) 601 N⋅m (443 ft⋅lb) rear-mounted electric motor with a copper rotor. 12 hp in kW =. 8.95 kW for mechanical hp. 8.83 kW for metric hp. 8.95 kW for electric hp US. 8.82 kW for electric hp Europe. 117.73 kW for boiler hp. Except for boiler hp, you may use the approximation kW = 3/4 × 12 hp. This rule of thumb is often accurate enough. And for 12 air or hydraulic horsepower, use hp (I). P h(kW) = (60 gpm) (110 ft) (1) / ((3960) (0.6)) = 27.8 hp. Shaft Pump 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. P s(kW) = P h(kW) / η (3) where . P s(kW) = shaft power (kW) η = pump efficiency How many kW is a 1 hp motor? One mechanical horsepower equals 0.7457 kilowatts. The mechanical horsepower also referred to as the imperial horsepower, is often defined as 745.7 watts or 550 ft.lbs/s. 1 kW = 0.28434514 Tons. In short, 1 kW is equal to 0.28334514 tons. Basically, 3.5 kW is equal to 1 ton. You can use a hand calculator to calculate that. We make things much easier for you by creating this kW to TR calculator and chart: kW To Tons Calculator. kW To Tons Chart. How to convert kilowatts to horsepower [kW to HP]: P HP = 1.34102209 × P kW. How many horsepower in a kilowatt: If P kW = 1 then P HP = 1.34102209 × 1 = 1.34102209 HP. How many horsepower in 76 kilowatts: If P kW = 76 then P HP = 1.34102209 × 76 = 101.91767884 HP. Note: Kilowatt is a metric unit of power. Horsepower is an imperial or United Enter how many hours per day you estimate you run your Air Conditioner. If it is less than one hour use a decimal. For example, 30 minutes would be .5 and 15 minutes would be .25. ‍ Power used (Watts) Input the wattage of your Air Conditioner. If you are unsure enter the average wattage for a Air Conditioner: 3,500. ‍ 1 horsepower (metric) (hp) is equal to 0.7355 kilowatt (kW). 1hp = 0.7355kW. The power P in kilowatt (kW) is equal to the power P in horsepower (hp) times 0.7355, that conversion formula: Pump Power Calculator in imperial Units/SI Units. P = power depend on: kW, H = head, m, Q = flow, m3/hr, SG = specific gravity, η= pump efficiency, decimal. k0ZLzN.
