Consider 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.
1-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.
