Steam is supplied to a fully loaded 100-hp turbine at 276 psia with u1=1,220.3 Btu/lbm, v1=3.65 ft3/lbm and υ1=466 ft/s. Exhaust is at 3 psia with u2=943 Btu/lbm, v2=392 ft3/lbm and υ2=1,128 ft/s. The heat loss from the steam in the turbine is -10 Btu/lbm. Neglect potential energy change and determine the work per lbm steam (unit should be ft⋅lbf/lbm ).
