Steam is flowing through a horizontal nozzle. At the inlet the velocity is $1000 mathrm{ft} / mathrm{s}$

Question:

Steam is flowing through a horizontal nozzle. At the inlet the velocity is $1000 \mathrm{ft} / \mathrm{s}$ and the enthalpy is $1320 \mathrm{Btu} / \mathrm{lb}_{\mathrm{m}}$. At the outlet the enthalpy is $1200 \mathrm{Btu} / \mathrm{lb}_{\mathrm{m}}$. If heat is lost through the nozzle at a rate of $5 \mathrm{Btu} / \mathrm{lb}_{\mathrm{m}}$ of steam, what is the outlet velocity?
