A manometer is used to measure the pressure of a gas filled rectangular tank as shown in
Fig. below. It is assumed that the mass density of fluid inside the tank is zero.

The manometric fluid is water having specific weight ‏دمر‎ If the local atmospheric
m

pressure is 100 kPa, the absolute pressure within the tank is:

400 cm
|

~|

500 cm

(A) 110 kPa (8) 115 kPa
(0. 11710೩ 0) 150kPa

For a two dimensional flow having velocity potential function ¢=4xy and stream function
y= = - x?) where x and y are in metres, the discharge between the stream lines passing

through the points (2,4) and (1,3) is:
(A) 20 m/s (B) 10 m%/s
(C) 8 3/8 (D) 16 83/8

Choose the wrong statement out of the followings mentioned connected with drag and lift
forces on immersed bodies :
(ಯ) For a stream lined body pressure drag is very small
(B) For a bluff body pressure drag is very large
(C) The drag force on slender cylindrical bodies decreases as velocity of flow increases
upto a Re = 2000
(D) Lift force occurs on a body when there is symmetry of fluid motion.
