1.A blunt object is streamlined primarily what?
a) reduce shear stress on the boundary
b) reduce the stagnation pressure
c) reduce the region of separated flow
d) reduce the maximum pressure on the object
2.A trapezoidal channel having bottom width of 8 m and side slopes of 1 : 1, carries a discharge of 80 m^3/s. Find the conjugate depth to an initial flow depth of 0.75 m before the jump. Also determine the energy loss in the hydraulic jump.
3.A horizontal channel 4 m wide carries a discharge of 16 m^3/s. Determine whether a jump may occur at an initial depth of 0.5 m or not. If a hydraulic jump occurs, determine the sequent depth (conjugate depth) to this initial depth. Also determine the energy loss in the hydraulic jump.
