33. An open drive condensing unit has the following factory delivered options. • Compressor maximum speed 550 rpm • Compressor pulley size 600mm • Factory supplied motor pulley size 200mm • Motor speed rating 1400 rpm Pre-commissioning tests suggest that the suction pressure is too high, the system capacity is below requirement, and the compressor speed needs to be increased. Assuming that the motor has an adequate power rating to drive the compressor to its maximum speed, what size motor pulley would be required to increase the compressor speed by an additional 10%? All calculations can be rounded to the nearest unit of 10. All calculations are to be shown

Task 2 A compression ignition engine operates has a compression ratio of 30 and uses air as the working fluid, the cut-off ratio is 1.5. The air at the beginning of the compression process is at 100 kPa and 30 C. If the maximum temperature of the cycle is 2000 °C. Assume cold air standard assumptions at room temperature (i.e., constant specific heat). A. Describe with the aid of diagrams the operational sequence of four stroke compression ignition engines. B. Explain the mechanical efficiency for an ideal diesel cycle of two and four stroke engines C. Explain the relationship between thermal efficiency (n), compression ratio (r), and cut-off ratio (re). D. Determine the net-work output, the thermal efficiency, and the mean effective pressure for the cycle. E. Determine the mean effective pressure (kPa) and net-power output (kW) in the cycle if a two- stroke engine is being used instead of a four-stroke engine.
An oil/gas separator is a pressure vessel used for separating a well stream into gaseous and liquid components. They are installed either in an onshore processing station or on an offshore platform. Based on the vessel configurations, the oil/gas separators can be divided into horizontal, vertical, or spherical separators. In a vertical tank, the heavy liquids are pumped out of the ____________ of the vessel and the light phase is drawn off the side of the tank. a. Inlet b. corner c. Bottom d. Top
Instruction: Show all your solution and Use the steam table, attached: https://drive.google.com/file/d/1I3WGlSBL7MbPkhEfJumTc2vCjvLfyXB6/view?usp=drivesdk A reheat cycle with two stages of reheating is executed, with steam expanding initially from 90 bar and 530°C. The two reheater pressures are 10 bar and 0.6 bar, and the steam leaves each reheater at 480°C. Condensation occurs at 0.03 bar. What is the steam flow rate in kg/s for an engine output of 20,000 kW?

Fourth task:During a visit to a factory, I came across a compressor and a compressed air networkUsed to operate a number of compressed air systems. The following notes were collected:• The compressor is relatively old.• The compressor room was very hot.• The compressor room was relatively close to the compressed air systems• The pressure at the outlet of the compressor was 8 bar.• The pressure in the pneumatic systems reached 7.5 bar.• Compressor on/off cycles every 40-55 seconds.Prepare a short, high-level recommendation note about actions that can be taken immediately, and measurements you might plan to assess potential energy savings opportunities.
