How much power is required to lift a {eq}25 \ kg {/eq} box to the top of a {eq}4 {/eq} meter flight of stairs in {eq}3.5 {/eq} seconds?Power:Power in physics is defined as the rate of doing work. In equation form
How much work is required to lift a 3.06 kg object from the bottom of a 8.5 m deep well? (a) What is the power output in watts and horsepower of a 70.0-kg sprinter who accelerates from rest to 10.0 m/s in 3.00 s? (b) Considering the amount of power generat...
k = 0.000133 A constant to yield power in kilowatts. (Multiplying the above kilowatt answer by 1.340 converts it to horse- power [i.e., 1 kW = 1.340 horsepower]). The rotor swept area, A, is important because the rotor is the part of the turbine that captures the wind energy. So,...
The furnace blower motor’s power draw is not expressed in watts. Rather, it is expressed inhorsepower (HP). In gas furnaces, we use1/6 HP, 1/3 HP, 1/2 HP, 3/4 HPand even1 HPmotors. When figuring out furnace fan wattage, we need to convert HP to watts (1 HP = 735.5 Watts...
So the power conversion of horsepower to watts is given by: P(W) = 746 ⋅ P(hp) Edited February 6, 2019 by AndyHull 1 Quote clockboy Moderator 8.7k Location: Gravesend, Kent Author Posted February 6, 2019 Thanks Andy much appreciated. I will purchase one later today. Quo...
Having already blown a large battery bank, we wanted better control over the charging sequence. So using the switch settings was not enough. Additionally, we now had the problem that when motoring at slow RPM with low batteries, the alternators consumed most of the engines available hors...
Based on what I am seeing, the Acceleration Boost looks like it adds about 50 or so horsepower and 50 lb ft of torque. If so, that is a lot of additional power for $2k. It would take a lot of hardware and tuning in an ICE based vehicle to achieve the s...
Drugs:I am assuming that the lifter is drug free. Drug use obviously makes these lifts easier to achieve. How much I don’t know for sure and it is likely to vary based on the individual, but if I had to guess I would say if drugs are used to reach a certain standard move its ...
1 gigawatt equals about: 3.1 million solar panels (320 watts each) 1.3 million horses (746 watts = 1 horsepower) 2,000 Chevrolet Corvette’s (650 horsepower each) 412 utility-scale wind turbines (2.43 megawatts each) 1 Nuclear reactor (0.5-1 gigawatt each) ...
A boy of mass 50 kg climbs up 29 steps each 20 cm high. How much work is done by the boy? (g = 10 m/s)Work Done:In Physics energy dissipation and work are done are different because we can dissipate the energy without moving between two positions ...
