| Example 1 : | |||||||||
A vertical gate of 5 m height and 3 m wide closes a tunnel running full with water. The pressure at the bottom of the gate is 195 kN/m 2 . Determine the total pressure on the gate and position of the centre of the pressure. |
|||||||||
| Solution : | |||||||||
| Given data: Area of the gate = 5x3 = 15 m 2 The equivalent height of water which gives a pressure intensity of 195 kN/m2 at the bottom. h = P/w =19.87m. Total force |
