Energy Required To Heat Water Calculator

This specific heat calculator is a tool that determines the heat capacity of a heated or a cooled sample.

Energy required to heat water calculator.

To calculate the heat required determine the variables. If we can calculate the volume of water and the required temperaure rise we can answer this question. C refers to the specific heat of the material. Heat required 5810 lbs x 1 btu lb ºf x 120 ºf 55 ºf.

Water is often used to store thermal energy. Your selection of a water heater using gallon s per day will have a energy cost savings per water heater over an estimated 13 year life expectancy compared to the model. Heat will transfer from a warm body with higher temperature to a colder body with lower temperature. Other units used to quantify heat are the british thermal unit btu the amount of heat to raise 1 lb of water by 1 o f and the calorie the amount of heat to raise 1 gram of water by 1 o c or 1 k.

98 c to 102 c this does not hold true any more. E c p dt m 1. δt refers to the temperature change that occurs. Heat energy required to heat 700 gal can be calculated as follows.

M mass of water heated 700 gallons 5810 lbs c p is the heat capacity of water 1 btu lb ºf given δt temperature difference 120 ºf 55 ºf. The following formula is used to calculate the power of heating element needed to heat a specific volume of water by a given temperature rise in 1 hour. Read on to learn how to apply the heat capacity formula correctly to obtain a valid result. M refers to the mass of the material.

2 c to 2 c or from fluid to gas e g. 1 btu 1 055 joules 252 calories 0 293 watt hour or the energy released by burning one match. It is approximately the energy needed to heat one pound of water by 1 degree fahrenheit. 1 watt is approximately 3 412 btu per hour.

E energy kj btu c p specific heat of water kj kg o c btu lb o f 4 2 kj kg o c 1 btu lb m o f for water. The british thermal unit or btu is an energy unit. With temperature difference. Q refers to the heat required.

Hi john it takes the same amount of energy to heat water from 48 degrees to 52 degrees as it takes to heat water from 58 degrees to 62. Energy stored or available in hot water can be calculated. Specific heat is the amount of thermal energy you need to supply to a sample weighing 1 kg to increase its temperature by 1 k. Heat energy the si unit of heat or energy is joule j.

But when the state of water changes from solid to fluid e g. You can calculate the energy required to raise the temperature of water or any given substance for that matter using this formula.
