The picture below shows a system where superheated vapor enters a container at a flow rate of 90 kg/s at 250C. The vapor is mixed with water (liquid phase) that enters at 20C.
A current of 1.35 A in an inductor L results in a stored energy of 0.135 J. The current is then changed to 6.48 A in the opposite direction. Calculate the change in the stored energy.
The tie rod AB and a pipe strut AC are used to support a 100-kN load as shown in the figure. Both members are made of structural steel (E = 200GPa). The cross-sectional areas are 620 mm2 for AB and 1,000 mm2 for AC.
The air is then heated until the piston is pushed agains the upper stops and the pressure of the air in the cylinder is 140kPa. Model the air as an ideal gas. Find the mass of the air in the cylinder.
Calculate the linear density of atoms along the [111] direction and the planar density of atoms in the (111) plane in BCC iron (rfe = 0.124 nm ) and FCC nickel (rni = 0.125 nm)
The air in the cylinder is then heated to a final temperature of 100 degrees celcius. Model the air as an ideal gas. Find the pressure needed to lift the piston off the stops.
