Question 1
If the free stream velocity is 3m/s and has a kinematic viscosity of 1.5 × 10-5 m2/s. What will be the boundary layer thickness at 1m?
Question 2
The maximum gauge pressure in a rectangular tank with square base of side L and height 2L filled with liquid of density ρ upto depth L which is accelerated in horizontal direction with acceleration equal to g/5 is expressed as kpgL. Find the value of k3 _________.
Question 3
The manometer shown contains two liquids. Liquid A has SG = 0.88 and liquid B has SG = 2.95. The deflection h, when the applied pressure difference is 
is
is Question 4
A thin plate of 20cmx20cm is kept horizontal between two plates, one is 2.6mm above it and another is 1mm below it. An oil of viscosity 0.027 Pa.s is kept on both side is flowing in different direction as shown in the figure. The horizontal force required to hold the plate in a fixed position is
Question 5
A pipe having diameters 30cm and 10cm at the two sections A and B carries water that flows at a rate 50 L/s. Section A is 8m above datum and section B is 4m above datum .If the pressure at section is 5bar find the pressure at section B
Question 6
A 200 m long naval ship has wetted area of 4000 m2. A model of this ship 8 m in length produces resistance of 100 N when velocity in fresh water with density 1000 kg/m3 is 5 m/s. The resistance R to the motion of ship is given by 
Where, symbols have their usual meaning.
If the propeller efficiency is 75%, then the shaft power required to propel the ship through sea water with density 1030 kg/m3 will be
