WebTo investigate the importance of the surface back-pressure, different values of back-pressure were introduced into Example 4-2. The results presented in Figure 4-37 shows how, at a constant injection rate, both the bottom-hole pressure and the foam quality at the bottom of the wellbore are affected by the surface back-pressure. As the back … WebCALCULATIONS The output power of the turbine depends on the mass flow rate of steam, the turbine efficiency, and the difference in enthalpy between the inlet and the exhaust of the turbine. In practice, the enthalpy of steam at the exhaust is determined by the backpressure and the turbine efficiency. Figure 2: Two-stage extraction a css property value is WebMay 1, 2024 · Abstract.
