Input(s)

E: Efficiency (dimensionless)

m: Mass Flow Rate $(\mathrm{lb} / \mathrm{ft})$ $\mathrm{h}_{\mathrm{o}}$: Outlet Enthalpy (btu/lb)

$\mathrm{h}_{\mathrm{i}}$: Inlet Enthalpy (btu/lb)

Output(s)

w: Work Done (btu)

Formula(s)

$$ \mathrm{w}=\mathrm{E} * \mathrm{~m} *\left(\mathrm{~h}_{\mathrm{o}}-\mathrm{h}_{\mathrm{i}}\right) $$
