Cavitation Problem

A sphere 1 foot in diameter is moving at a depth of 10 feet below a water surfacewhere the water temp is 50 degrees F. At what speed will cavitation first appear? Please show work and any assumptions.

Various mechanical engineering problems

Engineering Mechanics 1) The horizontal bar represented in figure is acted upon by the four vertical forces f1,f2,f3, and f4, whose location and characteristics are shown. Calculate the horizontal distance from point O at the base of F4 and horizontal line to the line of action of the resultant of the given forces. F1=400lbs, F2=3500lbs, F3=4500lbs , F4=3000lbs Between F1 and F2 is 6ft,between F2 and F3 is 6 ft, Between F3 and F4 is 8ft F1 F2 F3 F4 2) A railroad car that weighs 20,000 lb is traveling eastward with a velocity whose magnitude is 5fps. A second car, on the same track, that weighs 40,000 lbs also traveling in an easterly directi... click for more

Flow/momentum Problem

A hot gas stream enters a uniform diameter return bend as shown. The entrance velocity is 100 f/s, the gas density is .02lbm/cubic ft. and the mass flow rate is 1 lbm/cubic ft. The gas is cooled before exiting the bend ans exits the bend at a density of .06 lbm/cubic ft. The pressures at the entrance and exit of the bend are equal and are equal to atmospheric pressure. Find the force required to hold the bend. (See attached file for full problem description with diagram)

Fluid dynamics Problem

A closed tank full of a fluid of sp gr. 1.3 is accelerated downward at 2/3g and to the right at 1g. The dimensions of the tank are L=2.5m and H = 3m The tank is labeled as follows: Upper Left corner =D, Upper Right Corner =A , Lower Right Corner = B, Lower Left Corner = C. Find a) The pressure at point B - the pressure at point A B) The pressure at point C - the pressure at Point A --- See attachment for diagram. Use Euler eqn
