The total heat required when discharge temperature is below melting point.

\begin{equation}\label{eq:solid-load-charge-material-sensible-heat-cpp} Q_{solid} = m_{feed} \cdot (1 - f_{charged}) \cdot C_{p,solid} \cdot (T_{discharge} - T_{initial})\end{equation}

Symbols

\(Q_{solid}\)	Heat required for solid heating \([\unit{ \btu\per\hour}]\)
\(m_{feed}\)	Charge feed rate \([\unit{ \pound\per\hour}]\)
\(f_{charged}\)	Fraction of water charged \([\unit{ \unitless}]\)
\(C_{p,solid}\)	Specific heat of solid \([\unit{ \btu\per\pound\degreeFahrenheit}]\)
\(T_{discharge}\)	Discharge temperature \([\unit{ \degreeFahrenheit}]\)
\(T_{initial}\)	Initial temperature \([\unit{ \degreeFahrenheit}]\)
