For constant n, if the discharge is doubled, by what factor does the head loss increase?

figure below shows the proposed design for a hydraulic press used to compact solid waste. A piston at the right is capable of exerting a force of 12500 lb through connecting rod to the ram. The rod is straight and centrally loaded. it is made from AISI 1040 OQT 1100 steel (Sy=80x10^3 psi, E=30x10^6psi. compute the resulting design factor for this design. specify the required diameter of the connecting rod if it is made as a solid circular cross section. Use design factor of 4.0. ompute the resulting design factor 101 Solid waste to be compacted Emn A Ram Weld A-18m² I= 4.5int Connecting rod 12.75 ft Pin A 2.00 in Section A-A Piston 3.00 in 12 500 lb I= //12 H=4 n=0.

Not sure how to do this one. Would really appreciate a full solution. Thank you!

The figure below shows a fabricated assembly made from three different sizes of standard steel tubing listed in Appendix G.2. The larger tube on the left carries 0.075 m3/s of water. The tee branches into two smaller sections as shown. Reducing tee Flow 100-mm OD x 3.5-mm wall steel tube - 160-mm OD x 5.5-mm wall steel tube - 50-mm OD x 1.5-mm wall steel tube Required If the velocity in the 50-mm tube is 10.00 m/s, what is the velocity in the 100-mm tube to the nearest 1000th?
