calculate the mean piston speed (in mph) for a Ford Raptor engine running at 5800 rpm with a bore of 94mm and a stroke of 93mm Calculate the average acceleration imparted on the piston as it moves from TDC to 90 degrees ATDC

Can you help with question2

3. As shown in the Figure 12, for the variable speed cylinder, a and b are the oil inlet and c is the oil return port. It is already known that D3D200 mm, d1=160 mm and d=D40mm. The flow rate of the hydraulic pump is q-60L/ min. Calculation: the velocity of the piston when the pump only supplies oil to port a and the velocity of the piston when it supplies oil to port a and b at the same time. Figure 12

Q2/ A six-cylinder, gasoline engine operates on the four-stroke cycle. The bore of each cylinder is 80 mm and the stroke is 100 mm. The clearance volume per cylinder is 70 cc. At the speed of 4100 rpm, the fuel consumption is 5.5 gm/sec (or 19.8 kg/hr.) and the torque developed is 160 Nm. Calculate: (1) Brake power, (ii) The brake mean effective pressure, (iii) Brake thermal efficiency if the calorific value of the fuel is 44000 kJ/kg and (iv) The relative efficiency on a brake power basis assuming the engine works on the constant volume cycle = 1.4 for air. thon tected the following observations available :

Please provide correct solution plz

A power generator with two-cylinder, four-stroke gas engine has a bore of480 mm and a stroke of 585 mm. At 300 rev/min the torque developed is10 kNm. The generator is supplied with a mixture of gas and air in theproportion of 1 to 8 by volume. The estimated volumetric efficiency is 80% and the net calorific values of the fuel is 48.6 MJ/m3 Calculate:1 The brake power in kW2 the mean piston speed in m/s3 the break mean effective pressure in bar
