A pontoon of constant rectangular cross section is 50 m long, 10 m wide and 5 m in depth. It floats in sea water at a draught of 2 m with its C.G. 2.5 m above the base.
A mass of 10 tonnes is moved 20 m across the deck of an ocean vehicle of 10,000 tonnes displacement. The ocean vehicle has a rectangular tank 20 m long and 10 m wide containing sea water.
Determine the amount of heat transfer when this is done during a (i) constant volume process; (ii) a constant pressure process.
An oil pipeline was constructed to transport an oil with SG = 0.8 for a distance of 10 miles. The country was hilly, so the line made many ups and downs. These may be considered equivalent to 10 ris
What is the change of internal energy and enthalpy of 4 kg nitrogen as it changes from 50oC and 100kPa to 100oC and 200kPa?
A tank contains 2500 m3 of salt solution, with a salt concentration of 20 kg/m3. At time zero, salt free water starts to be pumped into the tank at a rate of 20 m3/min.
The crate slides down the section of the spiral ramp such that r = (0.5z) ft and z = (100 - 0.1t2) ft, where t is in seconds. If the rate of rotation about the z axis is ? = 0.04pt rad/s, determine
The air is now compressed in a polytropic process to 400kPa and 140oC. Determine the amount of heat transfer and identify if it is the heat loss or gain during this process.
A small high speed turbine operating on compressed air produces a power output of 100 W. The inlet state is 4 bar, 50 degrees Celsius, and the exit state is 1.5 bar, -30 degrees Celsius.
The truck travels in a circular path having a radius of 50 m at a speed of 4 m/s. For a short distance from s = 0, its speed is increased by v = (0.05s) m/s2, where s is in meters.
During a race the dirt bike was observed to leap up off the small hill at A at an angle of 60o from the horizontal. If the point of landing is 20 ft away, determine the approximate speed at which th
A particle moves along a hyperbolic path defined by the equation x2/16 - y2 = 28. If the x component of velocity is vx = 4 m/s, and remains constant, determine the magnitudes of the particle's veloc
