The velocity profile equation in Section 1 in a branched pipe stream is defined as follows: = , ( - 2 / ), = . Pipe diameters are displayed as D1 = 20 cm, D2 = 8cm and D3 = 4 cm, respectively. If the uniform velocity in Section 2 is u2 = 1 m / s, find the average velocity and direction of the current in Section 3.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
