　　Pressure Increases with Depth

　　Here is a picture of a tall cylinder with three holes under thefaucet。 The water keeps running from the faucet through the water tap into the cylinder。 As there are three holes in it， the cylinder can never be filled and keeps leaking water。

　　From the way water is corning out of the holes we can see pressure increases with depth。

　　Let us look at the first hole on the top。 As the hole is very near to the surface of water， the pressure at the top is not as high as that in the middle and at the bottom。 The water is coming out of the hole at an angle of 30 degrees。 It fails to the ground at a distance not far from the cylinder。

　　Now please have a look at the hole in the middle。 The hole is farther away from the surface of the water。 Here the water is deeper and so is the pressure。 As a result the falling water comes down with more force at an angle of 45 degrees。

　　Last and not least， I would like to call your attention to the hole at the bottom。 As it is deep at the bottom， the water receives the moist pressure。 The force of water coming out of the hole is strongest and it springs out at an angle of nearly 170 degrees falling down far away from the cylinder。

　　Now it is clear to me why man achieves success under great pressure， My dear friends， do not bo afraid of pressuro。 The more pressute， the more chance of success。

　　水压随水深而增大

　　这是一幅画，画的是水龙头下有3个孔的高高圆筒，水不断从水管通过龙头流入圆筒。因为筒上有3个孔，圆筒永远装不满，水不断泄出。

　　从水自孔中流出的情况，可以看到压力随水的深度而增大让我们看圆筒顶上的第1孔。因为离水面近，顶部的水压不如中间和底部的水压大。水从孔里成30度角涌出，落到离圆筒不远的'地方。

　　再看中间的孔。这里离水表面深一些，水较深，压力也较大。因此，水成45度角，以较大的力落下。

　　最后，但不是最不重要，请注意底部的孔。因为在底部深处，水压最大，流出孔时水力最强，成170度角冲出，落到离圆筒很远的地方。

　　现在，我明白了人为什么能在有巨大压力的情况下获得成功的道理。亲爱的朋友，不要害怕压力。压力越大，成功的机会就越多。
