Evaluate dimensional changes caused by a temperature variation.
Heat transfer · conduction
Calculate steady heat conduction through a homogeneous plane wall, or solve for the required thickness or thermal conductivity.
- Heat conduction calculator — Fourier's lawCalculate steady heat conduction through a homogeneous plane wall, or solve for the required thickness or thermal conductivity.
- Multilayer wall calculator — thermal resistanceCalculate steady conduction through 2 to 4 plane layers in series and see each layer's resistance and temperature drop.
- Cylindrical conduction calculator — pipe heat lossCalculate steady conduction through one homogeneous cylindrical layer from its inner diameter, thickness, conductivity and the temperature difference between its surfaces.
- Overall heat-transfer coefficient through a wallCalculate hot-fluid → wall → cold-fluid heat transfer by combining both convection resistances with conduction through one plane wall.
- Heat exchanger LMTD — duty, area and UCalculate the logarithmic mean temperature difference from four terminal temperatures, apply correction factor F, then solve Q̇, A or U.
Thermodynamics
Ideal gases and thermal energy without phase change.
- Latent heatFind the energy magnitude, transformed mass or specific latent heat in Q = mL. The model isolates a phase change and does not include heating or cooling before or after the transition.
- Thermal equilibrium temperatureFind the common final temperature of two isolated bodies with known masses, specific heats and initial temperatures. Signed heat values show which body gains or loses energy.
- Sensible heatCalculate Q = mcΔT to heat or cool a mass without a phase change. Enter specific heat and initial and final temperatures to find signed thermal energy.
- Ideal gas lawFind one unknown in PV = nRT from the other three quantities. Use absolute pressure and select your temperature unit: Celsius and Fahrenheit are converted to kelvins before calculation.
