Question 1:The velocity vector V at a point is given by 24i - 32j + 2k. Determine the resultant velocity.
Question 2:Determine the coefficient of discharge for a Venturimeter given a differential head of 18.6 m of water. Assume that 4% of the differential head is lost between the inlet and throat.
Question 3:The diameters of a pipe are 16 cm and 24 cm at sections 1 and 2 respectively. The velocity of water flowing through the pipe is 5 m/sec at section 1. Determine the discharge through the pipe and also the velocity of flow at section 2
Question 4:A pipe of 45 cm diameter carrying water, branches into two other pipes of diameters 28 cm and 24 cm respectively. If the average velocity in the 45 cm pipe is 2.4 m/sec, find the flow rate in this pipe. Also determine the velocity in the 24 cm pipe if the average velocity in the 28 cm pipe is 2.0 m/sec.
Question 5:A fluid flow field is given by V=x3 yi +y3 zj-(3xyz+ yz3 )k. Prove that it is a case of possible steady incompressible fluid flow. Calculate the velocity at the point (3, 2, 4).
