i need the answer quickly

Solve correctly please, H in t: Use the following hints to solve 8 (PV = nRT, CR = (T2 / T1)^(1 / γ)) The question is correct as well as the options, answer correctly. Wrong ans not allowed

Q1. A four stroke internal combustion engine has the following specifications: Brake power = effective pressure = 0.35 N/mm2;Maximum gas pressure = 3.5 N/mm2; Mechanical efficiency = 80 %. 7.5 kW; Speed = 1000 r.p.m.; Indicated mean %3D %3D Determine: 1. The dimesions of the cylinder, if the length of stroke is 1.4 times the bore of the cylinder; 2. Wall thickness of the cylinder, if the hoop stress is 35 MPa 3. Thickness of the cylinder head and the size of studs when the permissible stresses for the cylinder head and stud materials are 45 MPa and 65 MPa respectively

Problem 06.078 - Maximum efficiency of an electric generation station You are an engineer in an electric-generation station. You know that the flames in the boiler reach a temperature of 1225 K and that cooling water at 300 K is available from a nearby river. What is the maximum efficiency your plant will ever achieve? (Round the final answer to three decimal places.) The maximum efficiency of the plant is GOV Saved

Please , solve all two questions completely by clear handwritten

True Story! The 1998-1999 Mars Climate Orbiter mission was declared a total loss in1999 as there was a unit conversion mismatch error between Lockheed Martin and NASA. Themismatch was in the thruster force units. NASA used the SI system which called forNewton-Seconds (4.45 times as large) of thrust and Lockheed Martin used Pound-Force Seconds.Calculations placed the Orbiter at 68 miles from the surface as it went into orbit, but it waswithin 57 km of the surface after the breaking maneuver. Any distance from the surface lessthan 50 miles would have caused the Orbiter to crash.a. What was the actual distance of the Orbiter from the surface in miles?b. In percentage, how far off from the calculated 68 miles was the Orbiter?

b) The bore diameter of each cylinder in a sir-cylinder four-stroke internal combustion engine is 32 mm and the stroke of each piston is 125 mm. During testing, the engine runs at 1450 revolutions per minute (pm) with a pressure-volume indicator diagram showing a mean net area of 2 90 cm' and a diagram length of 0.85 cm. The pressure scale on the indicator diagram is set to 165 kNmper cm Calculate the mean effective pressure (mep) and the indicated power in klowatts (aW) developed by this six-cylinder four-stroke engine. Give your answer to 2 decimal places. c) A hollow connecting rod has an inner diameter of 26.25 mm and is subjected to an axial tensile load of 500 MN. the maximum allowable stress for this hollow rod is 325 KNimm, calculate the minimum thickness of the rod. Give your answer in millimetres (mm) and to 2 decimal places.
