The epicyclic gear train consists of the sun gear a which is in mesh with the planet gear b. this gear has an inner hub c which is fixed to b and in mesh with the fixed ring gear r. the connecting link de pinned to b and c is rotating at ωde = 18 rad/s about the pin at e.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation

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.

What is the main objective of using reheat rankine cycle?
