Question

Assume that the density of fresh water is 998 kg/m3 , and the density of salt water is 1025 kg/m3 . The gate weighs 0.448 kN/m (into the page). The gate is 5 m wide, into the page. Determine the height of the fresh water at which the gate opens. (15 points)

Answer 1

hello your question lacks the required diagram attached below is the diagram showing the resultant forces at the gate

answer: 1.975 m

Step-by-step explanation:

Given data :

density of fresh water = 998 kg/m^3

density of salt water = 1025 kg/m^3

gate weight = 0.448 kN/m ≈ 100 Ib/m

attached below is the detailed solution required
