The pipe elbow below discharges water at rate of SN/100 (m3/s) into the atmosphere at section 2. The total volume of the passage between sections 1 and 2 is equal to 0.2 m3 and the total mass of the elbow material between sections 1 and 2 is equal to 10 x SN (kg). Neglect any friction losses.
Calculate the horizontal and vertical forces acting on the elbow. Also, calculate the resultant force and angle of force on the elbow.
****SN=21
The diameter of a pipe changes gradually from 150mm at a point A, which is 6m above datum, to 75mm in diameter at point B, which is 3m above datum. The pressure at A is 103kPa and the velocity of flow is 3.6 m/s. The fluid flowing in the pipe is water. Neglecting losses, determine the pressure at B.
The increase in flow energy of a 10 ft3 of fluid passing a boundary of a system is 80,000 ft-lb. Determine the exit pressure if the inlet pressure is 100 psi.
