- The crate of mass m is supported on a cart of negligible mass as shown in (Figure 1). Determine the maximum force P that can be applied a distance d from the cart bottom without causing the crate to tip on the cart. Express your answer in terms of some, all, or none of the variables b, d, h, m, and the acceleration due to gravity g. P B harrow_forwardConsider a pair of pipes running in parallel, through which 1200 GPM flows, which have thefollowing features:Pipe 1: Carbon Steel, Schedule 40, 8" Diameter, 1200 GPM, Water at 44°F, Fittings:2 tees, 2 butterfly valves, 2 pressure gauges with their respective ball valves, 1 valvemotorized balloon. All valves are completely open. Length of the pipe is 6 feet. Pipe 2: consists of a carbon steel bypass pipe, schedule 40, diameter of 4",with the following accessories: 2 elbows long radius of 90° and an open globe valve.The length of the pipe is 10 feet. a) Determine the flow rate in each pipe.b) The pressure drop.arrow_forward1-ft3 of air is contained in a spring-loaded piston-cylinder device. The spring constant is 6 lbf/in, and thepiston diameter is 12 in. When no force is exerted by the spring on the piston, the state of the air is 250 psiaand 450◦F. This device is now cooled until the volume is one-third its original size. Determine the changein the specific internal energy and enthalpy of the air.arrow_forward
