Assume a ball is flying through air at rest. The speed of the centre of the ball is 5m/s (î). If the ball is spinning as shown below, find PB – PA. The ball has a radius (R) of 0.1m. Consider the speed of the ball to be constant as it passes through air. Let density of air be 1kg/m3. ω = 1(ĵ X î) rad/s.

Bernoulli's equation is a relation between pressure, kinetic energy, and gravitational potential energy of a fluid in a container.


Assume a ball is flying through air at rest. The speed of the centre of the ball is 5m/s (î). If the ball is spinning as shown below, find P<sub>B</sub> – P<sub>A</sub>. The ball has a radius (R) of 0.1m. Consider the speed of the ball to be constant as it passes through air. Let density of air be 1kg/m<sup>3</sup>. ω = 1(&jcirc; X î) rad/s.<br /><img src='https://www.fatskills.com/class11science/physics-questions-answers-fluids-mechanical-properties-bernoullis-equation-q8.webp' width='350' height='158' />
