APPSC Inspector of Factories Previous Papers
Hello sir I want to prepare for APPSC Inspector of Factories exam and here want Previous Paper for practice so can you please give me its details ? Hey as per your demand here I am giving you APPSC Inspector of Factories Previous Paper for your practice Here I am giving you question paper for practice The velocity distribution in turbulent flow follows a (1) parabolic law (2) logarithmic law (3) linear law (4) hyperbolic law Ans: (2) 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 Ans: (3) The Darcy â Weisbach friction factor âfâ 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 Ans: (4) 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 Ans: (3) In case of turbulent flow of a fluid through a circular tube, as compared to the case of laminar flow, at the same flow, rate, the maximum velocity is __________, shear stress at the wall is __________, and the pressure drop across a given length is________. (1) higher, higher, higher (2) higher, lower, lower (3) lower, higher, higher (3) lower, higher, lower Ans: (3) The hydraulic efficiency of an impulse turbine is maximum, when the velocity of wheel is ______ that of the jet velocity. (1) one-fourth (2) one-half (3) three-fourth (4) double Ans: (2) In a reaction turbine, the draft tube is used (1) to run the turbine full (2) to prevent air to enter the turbine (3) to increase the effective head of water (4) to transport water to downstream Ans: (3) In an inward flow reaction turbine (1) the water flows parallel to the axis of the wheel (2) the water enters at the centre of the wheel and from there flows towards the outer periphery of the wheel (3) the water enters the wheel at outer periphery, and then flows towards the centre of the wheel (4) the flow of water is partly radial and partly axial Ans: (3) In a Kaplan turbine runner, the number of blades are generally (1) 2 to 4 (2) 4 to 8 (3) 8 to 16 (4) 16 to 24 Ans: (2) The power developed by a turbine is (1) Directly proportional to H1/2 (2) Inversely proportional to H1/2 (3) Directly proportional to H3/2 (4) Inversely proportional to H3/2 Ans: (3) Here I am attaching PDF for complete paper APPSC Inspector of Factories Previous Papers Last edited by Neelurk; February 14th, 2020 at 01:25 PM. |
