Refrigerator shaft speed
Input(s)
N: Shaft Speed (rpm)
\(\mathrm{q}_{\mathrm{a}}\): Exhaust Turbine Volume \(\left(\mathrm{ft}^{3} / \mathrm{s}\right)\)
\(\mathrm{h}\): Isentropic Heat Change (btu/lb)
Output(s)
\(N_{s}\): Speed (rpm)
Formula(s)
\[
\mathrm{N}_{\mathrm{s}}=\frac{\mathrm{N} *\left(\mathrm{q}_{\mathrm{a}}^{0.5}\right)}{(\mathrm{A} * \mathrm{~h})^{0.75}}
\]
