made from 4” (10.2 cm) and 2 ½” (6.4 cm) diameter 1018 carbon steel pipe which were cut into ¾” (1.9 cm) wide rings. Surface areas tested ranged from 5.98 in2 (38.6 cm2) to 9.49 in2 (61.2 cm2). These rings were machined so that the outer diameter fit tightly
The volume of fluid in a pipe can be found given the inner diameter of the pipe and the length. To estimate pipe volume, use the following formula: volume = π × d 2 4 × h Thus, the volume of a pipe is equal to pi times the pipe diameter d squared over 4, times the length of the pipe h.

media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging.
Given diameter = 1.4 m Radius = 1.4 / 2 = 0.7 m Also h = 2.1 m We know that volume of tank = π r^2 h = 22/7 x 0.7 x 0.7 x2.1 Now dimensions of pipe will be Diameter = 3.5 cm Radius = D / 2 = 3.5 / 2 = 3.5 / 200 m Height = 2 m Now volume of water delivered in 1
