A compressor that has been in service for 20 years has finally broken down beyond repair, and now must be replaced. The old 180hp machine cost $1200 and its cost index at that time was 144.5. The new machine will be 400hp. How much will the new machine cost, given that today's compressor index is 252.4 and the power-sizing exponent for compressor sizing is 0.32?

The system shown below is to be designed for the gathering of gas. Well "A" is a following gas that will deliver 94.17 10' m'. The well "B" contains high gas-oil ratio wells, it is necessary to know that the compressor discharge pressure is 2.65 Mpa in order to deliver 61.09*10' m'. The pressure at the transmission line point is 2.07 Mpa gauge. Average following temperature will be (122 -158 °), compressibility factor (0.915-0.983), and that specific gravity of the following gas 0.69 and that of the other gas well is 0.71. The pressures at point "A and D" are 2.86, and 2.47 Mpa respectively. Estimate efficiency and the unknown values on figure. AL-? D-11.15 cm L-16.1 km D-?

A circumferential-groove pressure-fed bearing is lubricated with SAE grade 20 oil sup- plied at a gauge pressure of 30 psi. The journal diameter d; is 1.750 in, with a unilateral tolerance of -0.002 in. The central circumferential bushing has a diameter d of 1.753 in, with a unilateral tolerance of +0.004 in. The l' /d ratio of the two “half-bearings" that constitute the complete pressure-fed bearing is 1/2. The journal angular speed is 3000 rev/min, or 50 rev/s, and the radial steady load is 900 lbf. The external sump is maintained at 120°F as long as the necessary heat transfer does not exceed 800 Btu/h. (a) Find the steady-state average film temperature.
