A certain gas weighs 16.0 N/m3 at a certain temperature and pressure. What are the values of its density, specific volume, and specific gravity relative to air weighing 12.0 N/m3?
Also, at the failure cross sections the diameters are found to be 0.731 in., 0.645 in., and 0.587 in., respectively. Determine the percent elongation and percent reduction in area of each specimen.
A 2-inch diameter glass pipe is connected to a pipe network in which the pressure is 70 psig. If the length is 300 ft and the outlet is 10 ft above the pipe, determine the flow rate.
A large parabolic antenna is designed against wind load. During a wind storm, the maximum wind-induced pressure on the antenna, P, is computed as P= 1/2CRV^2 Where C = drag coefficient, R = air mass density in slugs/ft3,
The flywheel rotates with an angular velocity of omega = (4*theta^(1/2)) , where theta is in radians. Determine the time it takes to achieve an angular velocity of omega = 190 rad/s . When t = 0, theta = 1 rad .
