7.15.* The U-bend shown in Fig. 7.32 is connected to the rest of the piping system by flexible hoses. The ID of the pipe is 3 in. The fluid flowing is water, with an average velocity of 50 ft /s. The gauge pressure at point 1 is 30 psig and at point 2 is 20 psig. What is the horizontal component of the force in the support?

P1 P2 L3 11 12 L4 15 P3 A liquid flows through a pipe as shown above at a rate of 100 gpm. The entire piping system is 2inch inside diameter pipe Given: • The density of water is 62.4 lbm/ft3 ⚫ The specific gravity of the fluid is 0.75 • The viscosity of the fluid is 15 CP; The relative roughness of the piping is 0.0006 ⚫ Pressure gauge readings are in psig and P1 = 130 psig ⚫The piping system dimensions are as follows: L1-19ft; L2=36ft; L3-75ft; L4=10ft ; L5=18ft;

F1 F2 A2 P2 The following is known: Area, A1= 0.3 ft and A2= 7.6 A1- Assuming an incompressible fluid If a force F1 of 44.3 lbf / ft2 is applied at (1) then the resultant force, F2 in Ibf is equal to -- ?

Calculate the melting point of ice under a pressure of 10 MPa in Kelvin. Assume that the density of ice under these conditions is approximately 0.915g/cm and that of liquid water is 0.998 g/cm?.
