Question

Transcribed Image Text:The tank shown has a 0.1 m diameter circular plug which will pop out if the hydrostatic force on it reaches 550
N. Assume fluid is incompressible with specific weight = 9000 N/m3 water density = 1000 kg/m³, g = 9.81
m/s? h1= 0.02 m, neglect the plug weight. Take y-direction along the plug from point O, x-direction normal
to the paper, Mercury specific weight = 13.6, the top of the fluid is open to the atmosphere, the fluid under
hydrostatic condition.
Answer the following sub-questions:
Fluid
50
Manometer
Gate as a plug
with diameter
h1
= D
Mercury

Transcribed Image Text:The depth of the fluid (H, cm) when the plug pops out.
The area of the gate (plug, cm-).
78.53981
The location of the hydrostatic force when the plug pops out, (along y-axis) in cm, from point (O).
Second moment of inertia of the gate (plug, cm*) about its centroid.
490.873|
The manometer reading when the plug pops out (h, cm).
