This article is about penile erection. For the similar arousal in females, see clitoral erection. For other uses, see Erection (disambiguation). An erection (clinically: penile erection or penile tumescence) is a physiological phenomenon in which the penis becomes firmer, engorged and enlarged.
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).
1% as a decimal is 0.01 and hence the slope is 0.01. That means for a run of pipe of a certain length the rise must be 0.01 times the length. Thus for you example, since the length of the run is 80 feet which is 80 Ã 12 = 960 inches the rise must be 0.01 Ã 960 = 9.6 inches.
