Concept explainers

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem …

Textbook Question

Chapter 14, Problem 19P

* Siphoning water You want to siphon rainwater and melted snow from the cover of an above-ground swimming pool. The cover is 1.4 m above the ground. You have a plastic hose of 1.0-cm radius with one end in the water on the pool cover and the other end on the ground. (a) At what speed does water exit the hose? (b) If you want to empty the pool cover in half the time, what new hose radius should you use? (c) how much faster does the water flow through this wider pipe?

An estimated force-time curve for a baseball struck by a bat is shown in the figure below. Let F F(N) Fmax TÀ 0 t (ms) 0 la (a) the magnitude of the impulse delivered to the ball N.S (b) the average force exerted on the ball KN = 17,000 N, t = max a 1.5 ms, and t₁ = 2 ms. From this curve, determine the following.

There are many well-documented cases of people surviving falls from heights greater than 20.0 m. In one such case, a 55.0 kg woman survived a fall from a 10th floor balcony, 29.0 m above the ground, onto the garden below, where the soil had been turned in preparation for planting. Because of the "give" in the soil, which the woman compressed a distance of 15.0 cm upon impact, she survived the fall and was only briefly hospitalized. (a) Ignoring air resistance, what was her impact speed with the ground (in m/s)? m/s (b) What was the magnitude of her deceleration during the impact in terms of g? g (c) Assuming a constant acceleration, what was the time interval (in s) during which the soil brought her to a stop? S (d) What was the magnitude of the impulse (in N⚫ s) felt by the woman during impact? N⚫s (e) What was the magnitude of the average force (in N) felt by the woman during impact? N

Example Two charges, one with +10 μC of charge, and another with - 7.0 μC of charge are placed in line with each other and held at a fixed distance of 0.45 m. Where can you put a 3rd charge of +5 μC, so that the net force on the 3rd charge is zero?
