- 1.0 MPa 2.0 MPa 1.5 MPa Figure Q4a)The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke for each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm3 ); and calculate the clearance volume per cylinder for a compression ratio, r, of 8.75. b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm2 and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m2 per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine.Using unity conversion ratios, show that 1.00 lbm weighs 1.00 lbf on earth

- A 3000 pound force is applied to a piston causes a pressure of 800 psi. What is the diameter of the piston to which the force is applied?Kayla began a science experiment with 18 grams of an unknown solid. During the experiment, the change in the mass of the solid was – 7 grams. What was the mass of the solid at the end of the experiment? To solve the problem, Edna subtracted 18 – ( – 7 ) and came up with an answer of 25 grams. Is Edna correct? Why or why not? Yes, Edna is correct. No. The answer should have been – 25 grams, not 25 grams, because the mass of the solid decreased. No. Edna should have added 18 + ( – 7 ) because she needed to add the initial mass and the change in mass. SubmitThe specific volume of red brass is 0.001865 ft3/lb. Whatwould be its density?
