Experimental Study of Thermal Effect on Performance of PVC Pipes Using ANOVA Analysis

Abstract

In this study thermal effect at high pressure on Chlorinated Polyvinyl Chloride (CPVC) pipes studied where a test rig is built and the pipe has a diameter (d=0.5 in). The temperatures of water are varied (40, 60 and 80 cº) and the pressure is raised by using tester to reach (700 psi). The relationship between pressure and Reynolds number is discussed for the pipe used in this study with another pipe has a dimension (d= 0.75 in). ANOVA Analysis used to find the correlation of parameters effect the performance of CPVC pipes. The experimental results showed that the pressure drop increases with discharge increased at different values of temperature, when the pressure increased at constant temperature the friction losses is increased, where the values of friction losses were 4.8 ×10^-4 , 8×10^-4 and 2.4×10^-3 mm at 100, 300 and 500 psi respectively. Thus the pipe is damage at pressure (500 psi) and temperature (80 Cº) when the thickness is (3.1 mm).
