Answer:
F = 42325.17 N
Explanation:
We are given;
Radius of hemispheres; r = 0.38 m
Inner pressure; P_i = 17 milli bar
Outside Pressure; P_o = 950 milli bar
Now, net pressure; P_net = P_o - P_i
P_net = 950 - 17
P_net = 933 milli bar
From conversion rates, we know that;
1 milli bar = 100 N/m²
Thus;
P_net = 933 × 100
P_net = 93300 N/m²
Surface Area of hemisphere; A = πr²
A = π × 0.38²
Now, formula for pressure is;
P = F/A
Where F is force.
Thus making F the subject;
F = P × A
Plug in P_net and A to get;
F = 93300 × π × 0.38²
F = 42325.17 N
