Draw the Mohr circle for the stresses experienced by the surface of an internally pressurized steel tube that is subjected to tangential and axial stresses in the outer surface of 45,000 and 30,000 psi, respectively, and a torsional stress of 18,000 psi- see Figure P4.61.
Five kg of water is contained in a piston-cylinder assembly, initially at 5 bar and 240°C. The water is slowly heated at constant pressure to a final state. If the heat transfer for the process is 2960 kJ, determine the temperature at the final st..
Water flows from the container shown in Fig. P8.59. Determine the loss coefficient needed in the valve if the water is to "bubble up" 3 in. above the outlet pipe. The entrance is slightly rounded.
Consider a sphere with a diameter of 20 mm and a sur- face temperature of 60°C that is immersed in a fluid at a temperature of 30°C and a velocity of 2.5 m/s. Calculate the drag force and the heat rate when the fluid is
the velocity of a lift increases uniformly from zero to its maximum value at mid-height (1.4m) in 7.5s and then decreases uniformly to zero in 7.5s. The peak power output is 6kW when the velocity is maximum, determine the maximum lift force provid..
