During a reversible process, $10$ hp is being delivered ex$-$

$($E$)$ temal to the system. If the system energy is clanging by

$-10Bt\frac{u}{s},$ determine the rate of heat transfer.

$46$ The steam turbine shown in figure $4-34$ produces

$($E$)290Bt\frac{u}{l}bm$ of work while it loses $8Bt\frac{u}{l}bm$ of heat.

If the entering steam has an enthalpy value of

$1530Bt\frac{u}{l}bm$ and there is negligible kinetic energy

loss through the turbine, determine the enthalpy of exit$-$

ing steam.
