A single cylinder vertical engine has a bore of 30 cm and a stroke of 40 cm. The connecting rod is 100 cm long.
The mass of the reciprocating parts is 140 kg. On the expansion stroke with the crank at 300 from the top dead centre , the gas pressure is 0.7 Mpa.
If the engine runs at 250 rpm, find: (i) the net force acting on the piston (ii) resultant load on the gudgeon pin (iii) thrust on the cylinder walls (iv) the speed above which things remaining same, the gudgeon pin load would be reversed in direction.
a piston-cylinder device with a set of stops on the top initially contains 3 kg of air at 200 kpa and 27 degrees
If the engine exerts a traction force of 1/8 of the weight of the train, determine the speed of the train when it has traveled up the slope a distance of 1.1 . Neglect rolling resistance.
the acceleration a of a slider block and its displacement s are related by the expression a k s where k is a
an ideal vapor-compression refrigeration cycle opperates at steady state with refrigeratn 134a as the working fluid.
Silver Falls in the Green River Gorge has a sheer drop of 550 feet. Use the steady flow energy equation discussed in class to estimate the water temperature rise, in oF, resulting from the fall. Then estimate the temperature rise after the fall if th..
However, even when the cylinder is pressurized, the torque T is still sufficient to keep the seam closed so that no water leaks out. Determine the angle theta degrees that requires the minimum torque T to keep the seam closed. (Hint: use Mohr's ci..
