What is the formula of heat generator?

Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule’s equation of electrical heating.

How do you calculate the heat of electricity?

To calculate the wattage requirement to heat steel, use the following equation:

  1. Watts = 0.05 x Lbs of Steel x ΔT (in °F) / Heat-Up Time (in hrs)
  2. Watts = 3.1 x Gallons x ΔT (in °F) / Heat-Up Time (in hrs)
  3. Watts = 165 x Gallons Per Minute X ΔT (in °F)
  4. Watts = 1.35 x Gallons x ΔT (in °F) / Heat-Up Time (in hrs)

How do you calculate the heat load of electrical equipment?

Multiply the panel surface area times the BTU/hr. per square foot (or watts per square meter) to get the external heat transfer in BTU/hr or in watts. Sum the internal and external heat loads calculated.

How do you calculate heat dissipation in watts?

Solution:

  1. Surface Area = 2[(48×36) + (48×16) + (36×16)] divided by 144 = 42 square feet.
  2. Input Power = 300/42 = 7.1 Watts/SqFt.
  3. From Curve: Temp. Rise = 30°F (16.7°C)

Which formula is used to calculate the heat generated as per Joules law?

Joule’s Law states that H (Heat) = I (Current) x V (Voltage) x T (Time the current is allowed to flow). Or, written differently, H (Heat) = I2 (Current squared) x R (Resistance) x T (Time the current is allowed to flow).

How do you calculate the heat load of a heat exchanger?

The heat load of a heat exchanger can be derived from the following two formulas:

  1. Heat load, Theta and LMTD calculation. Where: P = heat load (btu/h)
  2. Heat transfer coefficient and design margin. The total overall heat transfer coefficient k is defined as:

How do you calculate kW heat for a room?

Room Heat Calculator

  1. Take the measurements of your room in feet or metres. The multiply the Length of the room x the Width of the room x the Height of the room.
  2. The multiply this figure by a factor of 6 for BTU’s or by 0.0606 for kW.
  3. The result is now the mimimum heat output required to heat this room.
