Afossil-fired power plant uses an ideal saturated rankine cycle with a steam flow rate of 6500 ibm/hr. the boiler pressure is 1500 psia; and the condenser pressure is 2 psia. the plant capacity factor is 80%. determine: (a) the feedwater pump specific work, (b) the net power output (in kw or mw) of the cycle, and (c) the plant thermodynamic efficiency

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk
