The obstacles in the menâs steeplechase are 914 millimetres (36.0 inches) high. In the womenâs steeplechase, the obstacles are 762 millimetres high (30.0 inches). The water jump consists of a barrier followed by a pit of water. The landing area for the pit of water is 3.66 metres (12.0 ft) by 0.70 metres (2.3 ft). At its deepest point, the slope goes down to a depth of 700mm (28 inches).
High flow rates over long periods of time can cause pipe erosion in the piping and especially in elbows and T fittings. Typically building codes limit the water velocity in hot water piping to 5 to 8 feet per second to prevent erosion of the pipe and fittings.Five feet per second is moving right along. At that velocity the hot water should reach a fixture connected to the water heater with a 100 foot pipe in about 20 seconds..74. 1.93. If your pipe is 3/4, then at 5 gallons per minute the flow rate would be 3.29 feet per second, so a 100 foot long pipe would require about 30 seconds. If the pipe was 1/2, then it would only take about 15 seconds to get the hot water through the 100 foot long pipe.
