Question

19. The pressure P on a disc immersed in a liquid varies as the depth d and the square of the radius r of the disc
The pressure is 2,800 Newtons/m². When the depth is 2.5 m and the radius is 2 m. What is the formula for
finding P?
A. P = 2.8 dr2
B. P = 28 dr2
C. A. P = 280 dr2
D. A. P= 2 800 dr?​

Answer 1

Answer:

For ∆ρ/ρ = 0.01, Equation 1 becomes 0.01 = ∆p 2.18 × 10 6 → ∆p = 2.18 × 10 4 kPa = 21.8 MPa 1.20. From the given data: T = 20 • C, D = 3 m, R = D/2 = 1.5 m, and ∆p = 9 MPa. For water at 20 • C, ρ 0 = 998.2 kg/m 3 ...
