Question

1) A production well was discharged and tested through an atmospheric silencer at sea level (1 bar
absolute) using a lip pipe with a diameter of 25 cm and a weir box with a 90 ° V-notch weir. The well was
flowing at a wellhead pressure of 6.5 bar gauge and the measured lip pipe pressure and weir height
were 3 bar gauge and 0.10 m, respectively. Calculate the discharge enthalpy and total mass flow of the
well.

2) answer A B AND C on the pic

4. A geothermal power plant with two production wells and one reinjection well is operating at a
separator pressure of 7 bar gauge, turbine inlet pressure of 6.5 bar gauge and condenser pressure of
0.10 bar absolute. Production well no. 1 has a mass flow rate of 35 kg/s and enthalpy of 2150 kJ/kg.
Production well no. 2 has a steam fraction of 64% and enthalpy of 1975 kJ/kg. Total mass flow entering
the separator is 88 kg/s. Isentropic efficiency of the turbine is 82%. The power plant's house load due to
pumps and compressors is 1.4 MW. (Note: Include solutions to your answers to get full credit).
