Rankine Cycle with Open Feedwater Heater (mass fraction)

(h1-h7)/(h4-h7)
Rankine Cycle with Open Feedwater Heater (Wnet)

m(h3-h4)+(1-a)m(h4-h5)+(1-a)m(h6-h7)+am(h1-h2)
Otto Cycle
- Use isentropic relations for volume, not pressure!
- Temperature at State 3 found from using the heat added by combustion
- Pressure then found at State 3 from ideal gas formula
Diesel Cycle
- From States 1 & 2 Otto Cycle & Diesel are the same
- State 3 is found from Cp(h3-h2) since it is a constant pressure process
- Then we can find the volume at State 3 in order to calculate the isentropic relations between State 3 & 4.
Mean effective pressure (labeled as Peff)

Peff=(v1-v2)/Wnet
