Question 1

The value of coefficient of discharge for a venturi meter usually lies between:

Question 2

Bernoulli equation is applicable

Question 3

A hemispherical tank of radius R has an orifice of cross-sectional area ‘a’ at the bottom and is full of liquid. The time required to empty the tank completrly is given by ( $Description: E:\Gate\SSC JE Civil Part 1-Done\04_FM_BLok_files\image138.png$ =coefficient discharge)

Question 4

A venturimeter having a throat diameter of 0.1 m is used to estimate the flow rate of a horizontal pipe having a diameter of 0.2 m. For an observed pressure difference of 2 m of water head and coefficient of discharge equal to unity, assuming that the energy losses are negligible, the flow rate (in m³/s) through the pipe is approximately equal to

Question 5

A horizontal nozzle of 30 mm diameter discharges a steady jet of water into the atmosphere at a rate of 15 liters per second. The diameter of inlet to the nozzle is 100 mm. The jet Impinges normal to a flat stationary plate held close to the nozzle end. Neglecting air friction and considering the density of water as 1000 kg/m³, force exerted by the jet (in N) on the plate is _______

Question 6

The maximum size of sand particles (with relative density of 2.65) which will settle in water, according to Stoke’s law, is ___________mm.
(Density of water = 998 $Description: E:\Gate\SSC JE Civil Part 1-Done\04_FM_BLok_files\image056.png$ , Dynamic viscosity = $Description: E:\Gate\SSC JE Civil Part 1-Done\04_FM_BLok_files\image087.png$ Pa.s).
