Question

Per Bernoulli's Principle, low velocity = ____ pressure.

A. high
B. medium
C. low
D. no

Answer 1

A. high pressure

Step-by-step explanation:

Bernoulli's equation is given as;

`P_2 + (1)/(2) \rho v_2^2 + \rho gh_2 = P_1 + (1)/(2) \rho v_1^2 + \rho gh_1\\\\P_2 = P_1 + (1)/(2)\rho (v_1^2 - v_2^2) + \rho g(h_1-h_2)`

Based on the equation above, it can be seen that an increase in velocity (from v₁ to v₂ ) causes a decrease in pressure (P₂), while a decrease in velocity will cause an increase in pressure.

Therefore, Per Bernoulli's Principle, low velocity = high pressure.
