One kilowatt equals how many btu per hour?
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
How many liters are there in a kettle?
1.5-2.2 litres
If a tv screen has 525 scan line and and aspect ratio of 3 is to 4 and if each pixel contains 12bits worth of intensity information how many bits per second required to 30 frames each second?
They will require 24 bits per second to 30 frames each second.
When you run the 100 meter dash in 10.2 seconds how many meters do you go with each second?
9.804 meters per second.
How many joules are needed to warm 25.5 grams of water from 14.0C to 22.5C?
9.1x10^2J
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.
How many joules are in 59.4 watts?
"59.4 watts" means "59.4 joules every second"
How many joules does the sun release in one second?
It is approx 3.82*10^26 Joules.
How many kilocaclories of heat does the operation of a 1190 watt hair dryer produces each second?
Watts means joules per second. The device uses 1190 joules of energy every second; most of that will be converted to heat. It is best to use SI units most of the time; in this case, joules rather than calories for energy. However, if you want to convert that, 1 calorie = 4.184 joules; thus, you can divide the number of joules by 4.184 to convert it to calories.
How many joules do you need each day?
1000
Does a 150 watt bulb do 150 joules of work?
Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.
10 kw equals how many joule per second?
10,000 joules per second.
How many units per hour utilized by a 45kw motor?
watt (w) means joules per second. kW (kilowatts) means thousands of joules per second. Multiply that by 3600 to get the joules used per hour.
How many joules of light energy are in 1440 watts of electrical energy?
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.
