Thermodynamics Calculators

Ideal gas law, thermodynamic cycles, entropy, steam tables, and psychrometrics

Solve for P, V, n, or T using PV = nRT with unit conversions for pressure, volume, and temperature

Calculate isentropic process relations between states using P, V, T and the specific heat ratio γ

Calculate Carnot cycle efficiency, net work, and required temperatures for a given efficiency

Calculate Otto cycle thermal efficiency and state-point temperatures and pressures from compression ratio

Calculate Diesel cycle thermal efficiency from compression ratio, cutoff ratio, and specific heat ratio

Calculate Rankine cycle efficiency, turbine work, pump work, and heat input from state-point enthalpies

Solve for Q_in, Q_out, W_net, or efficiency given any two of the four heat engine quantities

Calculate coefficient of performance for refrigerators and heat pumps, including Carnot COP from temperatures

Calculate humidity ratio, dew point, enthalpy, and specific volume from dry-bulb temperature and relative humidity

Interpolate saturated water properties (P_sat, v_f, v_g, h_f, h_fg, h_g, s_f, s_g) from built-in steam tables

Pressure-based saturated steam table lookup: enter P_sat → interpolated T_sat, v_f, v_g, h_f, h_fg, h_g, s_f, s_fg, s_g
