Can you provide me previous year question paper with Key for the post of AEE or Assistant Executive Engineers for preparation of APPSC or Andhra Pradesh public service commission?

The previous year question paper with Key for the post of AEE or Assistant Executive Engineers for preparation of APPSC or Andhra Pradesh public service commission is as follows:

The lower limit of the critical Reynolds number below which all disturbances in pipe flow are

damped out by viscous action has a value approximately equal to
(1) 1 (2) 500 (3) 1000 (4) 2000

The most essential feature of a turbulent flow is
(1) large discharge
(2) High velocity
(3) velocity and pressure at a point exhibit irregular fluctuations of high frequency
(4) velocity at a point remains constant with time

Steel and cast iron pipes carrying fluid under pressure are regarded as hydraulically smooth when
(1) the boundary surface is relatively smooth
(2) the roughness projections are of low height
(3) the roughness elements are completely covered by the laminar sub-layer
(4) the laminar layer is thin as compared to the average height of roughness elements

The Darcy – Weisbach friction factor ‘f’ which is a direct measure of resistance to flow in pipes is dependant on
(1) roughness height, diameter and velocity
(2) relative roughness, diameter and viscosity
(3) relative roughness, velocity and viscosity
(4) relative height, diameter, velocity and kinematic viscosity

The parameters which determine the friction factor for turbulent flow in a rough pipe are
(1) Froude number and relative roughness
(2) Froude number and Mach number
(3) Reynolds number and relative roughness
(4) Mach number and relative roughness
