- 10 00 R %24 Homework 6 3.Water is flowing in a pipe that has varying cross-sectional area throughout, and at all points the pipe is completely filled with water. At one point the cross-sectional area of the pipe is 0.07 m^^2, and the velocity of the fluid is 3.50 m/s. What is the fluid velocity in the pipe where the cross sectional area is instead (a) 0.105 m^2 and (b) 0.067 m^2. (c) also calculate the volume discharged from the end of the pipe in one hour (Hint: Use volume flow rate eq. V/t=A*v and solve for V) Q=AV 0.105*0.067= f12 f8 114 A f4 十百 & 7. 4.A3X Exit full screen Press Esc to exit full screen What is The resulant Force exerted on the slave piston of 25 squate meters? ! 20 New tons Applied on Masfer piston of 25 square Centimeters Hy draulics - drawing Give an exect answer is Nor to scale. and include units.
