If piston diameter of an oleo system is given by 20 unit then, find the approximate value of typical external diameter of the same oleo system.

If piston diameter of an oleo system is given by 20 unit then, find the approximate value of typical external diameter of the same oleo system. Correct Answer 26 unit

Approximate value of external diameter can be given by, D = piston diameter + 0.3* piston diameter = 20 + 0.3*20 = 26 unit.

Air at a constant pressure in a piston-cylinder is at 300 K, 300 kPa and V=0.1 m^3. It is heated to 600 K in 30 seconds in a process with constant piston velocity. Find the power delivered to the piston.
A piston-cylinder contains 1 kg of liquid water at 300 kPa, 20°C. Initially the piston floats, with a maximum enclosed volume of 0.002 m3 if the piston touches the stops. Now heat is added so that the final pressure is 600 kPa. Find the work in the process.
A piston/cylinder has 5m of liquid 20°C water on top of piston with cross-sectional area of 0.1 m2. Air is let in under the piston that rises and pushes the water out. Find the necessary work to push all the water out.
A piston-cylinder has the piston loaded with outside atmospheric pressure and piston mass to a pressure of 150 kPa. It contains water at −2°C, which is heated until the water becomes saturated vapour. Find the specific work for the process.
