For example, if I use a 1/2″ pipe size, I got the friction loss and velocity of 22 ft and 5 fps respectively. The friction of water against the walls of the pipe fights against the pressure from the water supply. If the wrong type of pipe is selected, damage during construction is possible and the system may have a less than planned service life. Per Dunn and Kew [4], the design of a heat pipe or thermosyphon to fulfill a. particular duty involves four broad processes: 1. Rock and Slag: Rock and slag fibres are bonded together with a heat resistant • Schedule 80 pipe will provide greater factor of safety allowing it to handle much higher design pressures.
