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?
To find the number of photons being radiated per second, you need to calculate the energy of each photon first. Since the light bulb emits 100 watts (100 joules per second), and each photon has an energy of about 4.86 x 10^-19 joules for visible light, you can divide the total energy emitted per second by the energy of each photon to find the number of photons emitted.
How many joules are in 100 watts?
There are 100 joules in 1 watt-second, so in 1 second, there would be 100 joules per watt. Therefore, in 100 watts, there would be 10,000 joules.
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 joules do you need each day?
1000
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 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.
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 joules of light energy are in 1440 watts of electrical energy?
To calculate the energy in joules, you can use the formula: energy (joules) = power (watts) × time (seconds). If you have 1440 watts of electrical power and want to calculate the energy in joules for a specific time period, you would need to know the time duration in seconds.
Does a 150 watt bulb do 150 joules of work?
No, a 150 watt bulb consumes 150 watts of power, which is equivalent to 150 joules per second. The work done by the bulb depends on the time it operates for.
How many joules are there in a kilojoule?
A Joule is a Watt-second (or W=J/s). Therefore, 3.5 kWh = 3.5*3600 kWs = 3.5*3600*1000 W-s = 12.6 million Joules
