Air of density 1.2 kg/m³ flows horizontally. If the speed increases from 10 m/s to 20 m/s, what is the resulting decrease in pressure?
Q1. Air of density 1.2 kg/m³ flows horizontally. If the speed increases from 10 m/s to 20 m/s, what is the resulting decrease in pressure?
Answer: 180 Pa
Explanation: Using Bernoulli's equation for horizontal flow, ΔP = 0.5 * ρ * (v2² - v1²). Here, 0.5 * 1.2 * (400 - 100) equals 180 Pa.
