Overview

Engineering reference data for Heat Load Steam Pipes Water in heat transfer.

Key Formulas

Fourier's Law

$q = -k \nabla T$

Heat flux proportional to temperature gradient.

Convective Heat Transfer

$Q = hA(T_s - T_\infty)$

Heat transfer between surface and fluid.

Cylindrical Pipe Heat Loss

$\frac{Q}{L} = \frac{2\pi k (T_i - T_o)}{\ln(r_o / r_i)}$

Heat loss per unit length through a pipe wall.

Steam Condensation Heat

$Q = \dot{m}_s \cdot h_{fg}$

Heat released when steam condenses inside the pipe.
