1.A particle travels along a straight line with a constant acceleration. When s=4ft, v=3ft/s and when s=10ft, v=8ft/s. Determine the velocity as a function of position.
2.Atmospheric air is at 101 kPa (abs) and 25 degrees C. Determine (a) the density of the air (b) the molar specific volume of the air. Work out problem completely please. I already have the answers a) 1.18 kg/m^3 b) 24.5 m^3/kmol
3.A spherical pressure vessel has an outer diameter of 10 ft and a wall thickness of 0.5 in. knowing that for the steel used ?all= 12 ski, E= 29 x 10^6 psi, and v= 0.29, determine
(a) the allowable gage pressure,
(b) the corresponding increase in the diameter of the vessel.
