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 114AP

The left ventricle of a resting adult's heart pumps blood at a flow rate of 83.0 cm³/s , increasing its pressure by 110 mm Hg, its speed from zero to 30.0 cm/s, and its height by 5.00 cm. (All cumbers are averaged over the entire heartbeat) Calculate the total power output of left ventricle. Note that most of the power is used to increase blood pressure.

The left ventricle of a resting adults heart pumps blood at a flow rate of 81.0 cm^3/s, increasing its pressure by 110 mm Hg, it's velocity from zero to 35.0 cm/s and it's height by 5.00 cm. ( all numbers are averaged over the entire heartbeat ) Calculate the total power output ( in W) of the left ventricle. Note that most of the power is used to increase blood pressure.

The power output of the heart is given by the product of the average blood pressure, 1.33 N/cm², and the flow rate, 105 cm³/s. Find the power of the heart. Give your answer in watts.

The left ventricle of a resting adult's heart pumps blood at a flow rate of 87.0 cm3/s, increasing its pressure by 110 mm Hg, its velocity from zero to 25.0 cm/s, and its height by 5.00 cm. (All numbers are averaged over the entire heartbeat.) Calculate the total power output of the left ventricle. Note that most of the power is used to increase blood pressure.
