Step by step
Solved in 3 steps
- Steam is supplied to a fully loaded 100-hp turbine at 200 psia with u; = 1163.3 Btu/lb, v; = 2.65 ft³/lb and u1 = 400 ft/s. Exhaust is at 1 psia with uz = 925 BTU/lb, v2 = 294 ft2/lb and uz = 1100 ft/s. The heat loss from the steam in the turbine is 10 Btu/lb. Neglect potential energy change. Determine: a. the work per Ib steam b. the steam flow rate in Ib/hr u, = 1163.3 Btu/lb u, = 925 BTU/lb V, = 2.65 ft /lb v, = 294 ft /lb P,= 200 psia Turbine P2= 1 psiaA nuclear power plant operates at 75 % of its maximum theoretical (Carnot) efficiency between temperatures of 645 °C and 380 °C. 1. If the plant produces electric energy at the rate of 1.6 GW, how much exhaust heat is discharged per hour?If you have 6 moles of a diatomic ideal gas (such as oxygen or nitrogen), how much heat is required to raise the temperature of this gas from 261.5K to 282K if the volume of the gas remains constant during the heating?
