If it takes 7460 W to two a certain boat at a speed of 4 kmph, how much horse power (1 H.P = 746 watts) will be required to tow it at a speed of 12 kmph ? [Hint : Force ∝ velocity P = force × velocity] View Solution What is the relation between a watt (W) and a ...
Convert 10W to electrical horsepower: P(hp)= 10W / 746 = 0.013405 hp Watts to metric horsepower One metric horsepower is equal to 735.49875 watts: 1 hp(M) = 735.49875 W So the power conversion of watts to horsepower is given by: P(hp)=P(W)/ 735.49875 Example Convert 10W to metric h...
Where P is the power in watts (or joules per second), V is the potential difference in volts, and I is the current in amperes. Power can also be expressed in volt-amperes and horsepower (HP), with the latter often used in everyday engines such as those in motor vehicles. 1 HP is ...
Interestingly, the question of "how much hp does a turbo add?" is not just about power anymore; modern turbos enhance fuel economy as well, making smaller engines more efficient while still maintaining the ability to achieve highway speeds. This shift not only demonstrates how turbochargers can...
How Much Power Do Common Devices Need? Desktop computer: On average, a desktop computer with amonitorwill consume around 200 watts. Got a bigger screen? That number might rise to around 250 watts. Large color TV: A large color TV also hovers around the 200-250 watt range. ...
The refrigerant in gas form then enters the compressor, where it is pressurized and the whole process starts all over again. If the system uses an orifice tube, there will be an accumulator between the evaporator and the compressor. An orifice tube sometimes lets too much refrigerant into the...
Small mini-splits for a single room might draw as little as a few hundred watts, while the largest, least-efficient models consistently pull 7.5 kW. Those are some huge ranges. Below, we’ll walk you through a few ways to estimate how much energy a heat pump will use in your ...
How much power does a laptop use when plugged in? While notebooks andnetbooksgenerally use less power than high-end laptops, the power consumption of a laptop depends on the size of the screen and specs, typically you will find power consumption as low as 20 watts and up to 100 watts whe...
Sustained hard disk usage consumes an average of around 5 percent of total power consumption in a mobile PC. New solid-state drives are much more efficient, because there is no mechanical mechanism and there are no platters spinning. Hybrid drives that have a solid-state and disk...
A machine puts out 100 watts of power for every 1,000 watts put into it. What is the efficiency of the machine? The intensity of a radiation beam is measured as 419 kW/m^2. If a 4.37 m^2 area is irradiated for 5.9 s, how much energy is transferred to the area?
