Valve Maintenance-4-4

Hi there sir/madam I'm not sure how to do this question could please help with this The bore diameter of each cylinder in a six-cylinder four-stroke petrol engine is 25 mm and the stroke length for each cylinder piston is 275 mm. During engine testing, the engine runs at 4250 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 7.85 cm2 and diagram length of 3.25 cm. For a pressure scale set at 525 kN/m2 per cm on the indicator diagram, calculate the indicated power developed by the engine. To 2 d.p

What would an isometric of the oxygen piping system below look like, where PSA GEN = Pressure Swing Adsorption Oxygen Generator (PSA) COMPs = Compressors POMPs = Pumps HEAT = Heat Exchanger PV = Flow Valves ST TANK = Storage Tank VENT = Vent DR = Drains PSV = Pressure Relief Valve In addition, what would be the possible problems that would require flexibility correction by adding expansion joints, spring supports, anchors and brackets?

what is an air preheater, what are formulas, and their importance, define the diagram, and give me a script on how to explain the design of an air preheater, and how did values end up in that number. based on standards

Using the jet engine lecture notes and its charts, derive a mathematical expression relating a jet engine’s dry weight with its take-off thrust. Write the expression in imperial units and then convert it to SI units.

Two cylinders act right after one another. Each cylinder is metered, and some actions are slow, and there is a dwell between some actions. What is the minimum flow rate required (CFM) to operate this cylinders? (enter answer with 2 decimal places) Sequence of operations: Cyl. A extends with metering (takes 1.5 second) Dwell time for 2 seconds for part machining Cyl. B extend and retracts without metering (2 second) Dwell time for 10 seconds while an electric mixer is operated Cyl. A retracts quicky with no metering (0.5 seconds) Dwell time for 5 seconds while a part is placed before next cycle   Assuming the displacements of the cylinders are: Cyl. A DE = 65 in3 Cyl. A DR = 62 in3 Cyl. B DE = 44 in3 Cyl. B DR = 41 in3
