Using the methane P-H diagram please provide the following info for a 1 stage gas compre mass flow rate Inlet pressure Inlet temperature adiabatic efficiency Outlet pressure Compression Ratio Please Find the following: Inlet specific volume Inlet volumetric flow Inlet H Outlet H, ideal Outlet H, real Outlet Temperature (ideal) Outlet Temperature (real) Outlet specific volume (real) delta H ideal delta H real HHP BHP SHP 305 406.6666667 0.5 m3/kg 10.417 m3/s 725 305 1030 KJ/kg 1131.7 KJ/kg 330 k 370 k 0.1 kJ/kg KJ/kg 6354.17 KW 8472.22 KW 8645.12 KW Costs $4,000 per KW Total Cost $34,580,498.87 million Part 2 m3/kg use the ideal delta H use the real delta H shaft efficiency The plant manager is stinken worried about the cost of the compressor and asks you if the is anyway to reduce the cost of the compressor. Describe what you suggest and skecth what you would do. o for a 1 stage gas compressor hello !!!!! HW #9 mass flow rate Inlet pressure Inlet temperature adiabatic efficiency Outlet pressure Compression Ratio 75,000 kg/h 0.18 MPa 180 K 75% 2 Mpa 11.11111111 probably a bit less than 0.1 use the ideal delta H use the real delta H shaft efficiency 98% Turbines turbo-expanders let down valves boundary layers von Karman Integral Analysis gral Analysis Given a Super Pressure Steam Header (SPS) header of 1800 psia and 1200 F as shown in the sketch below. Assuming an exit pressure as in the cases indicated please calculate the AWR (actual water rate). Also please plot the AWR versus the exit pressure and compose a sentence or two about what you have learned from this exercise. Inlet Steam SPS Header P, psia T, F HP, HT Steam Outlet Steam P, psia AWR, lb/h steam per kW work use 70% as the turbine efficiency Lower Pressure, Lower Temperature Steam e sketch below. hat you have 1800 1200 WR, lb/h steam per kW 300 ???? 200 ???? se 70% as the turbine efficiency where did you drop your lunch? somewhere in there ! 100 ???? 60 ???? Prob #1 Stream 1 2 T, F P, psia lb mol/h lbs/h 100 40 2315 62500 250 125 2315 62500 0.18 0.98 1.19 27 0.443 0.97 1.165 27 3 density, lbs/ft compressibility factor, Z k MW Please specify the frame size, number of impellers, the polytropic head, the speed, the Gas Horsepower (HHP, BHP, SHP), and the cost Prob #2 Describe the difference between the "n" method and the Mollier method to calculate the specifics of a centrifugal compressor. Which do you think is better and why? ...
