Determine the heat rate if vapor enters a rotor at 400°F and departs at 200°F at atmospheric pressure. During a typical operation, 500 lb of steam passes through the rotor every hour. ΔT = 400 – 200. ΔT = 200°F. We have the Formula, Rh = Ws × c × ΔT. Rh = 500 × 0.48 × 200. That equals, Rh = 48000 btu/hr. fingers feel stiff and numb
