In a steam turbine, steam from a steam generator or boiler impacts on the turbine blades (Figure 4.3). Therefore, the heights can be considered the same. Then the general equation reduces to: 1 È ˘ Q = m Í(U 2 - U1 ) + ( p2V2 - p1V1 ) + (J 22 - J12 )˙ + W 2 Î ˚ 1 È ˘ Q = m Í( H 2 - H1 ) + (J 22 - J12 )˙ + W 2 Î ˚Get price
