MODEL ANSWER PAPER
Q.1 Derive expression for pressure variation in a fluid at rest (5)
Q.2 Derive Total pressure force and centre of pressure for Vertical plane submerged in water (5)
Q.3 Explain different type of flow (5)
Q.4 The velocity vector in a fluid flow is given V= 4x3i- 10x2yj + 2tk Find the velocity and acceleration of fluid particle at (2,1,3) at time t=1 (5)
Q.5 A30 cm diameter pipe, conveying water, branches into two pipes of diameters 20 cm and 15 cm respectively. If the average velocity in the 30 cm diameter pipe is 2.5 m/s, find the discharge in pipe. Also determine the velocity in 15 cm pipe if the average velocity in 20 cm diameter pipe is 2m/s. (5)
