The 2415-kg anvil A of the drop forge is mounted on a nest of heavy coil springs having a combined stiffness of 3.0(106) N/m. The 565-kg hammer B falls 500 mm from rest and strikes the anvil, which suffers a maximum downward deflection of 30 mm from its equilibrium position. Determine the height h of rebound of the hammer and the coefficient of restitution e which applies.

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.

Apreheater involves the use of condensing steam at 100°c on the inside of a bank of tubes to heat air that enters at 1 atm and 25°c. the air moves at 5 m/s in cross flow over the tubes. each tube is 1 m long and has an outside diameter of 10 mm. what is the minimum value of nl needed to achieve an outlet temperature of t 75 c? what is the corresponding pressure drop across the tube bank?
