Choose a characteristic of turbulent flow below. a. Laminar flow b. Produces kinetic energy c. Viscosity dominates the flowals behavior d. The energy will always be potential energy e. Fluids moving at different rates of speed when they go through or around a solid object

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
