if a tube has area a1 at the left and and pressure P1 and the right has area a2 and is raised to height h ,If the fluid has speed v1 at the left end can i write a1v1=a2v2 and P2=P1+pgh

Fluid mechanics is the branch of physics that deals with the study of fluids (liquids and gases) and their behavior in motion or at rest. It involves the application of mathematical equations and principles to understand and predict the behavior of fluids.
Pressure is defined as the force exerted by a fluid per unit area. It is a crucial concept in fluid mechanics as it influences the flow and behavior of fluids. Pressure can be measured in various units such as Pascals (Pa), atmospheres (atm), or pounds per square inch (psi).
According to Bernoulli's principle, an increase in fluid velocity results in a decrease in pressure. This means that as a fluid flows faster, its pressure decreases. Similarly, a decrease in fluid velocity results in an increase in pressure.
Yes, pressure can be negative in fluid mechanics. In cases where fluid is moving in the opposite direction of the force applied, the pressure can be negative. This is also known as suction pressure.
Fluid mechanics and pressure have numerous real-life applications, such as in the design of airplanes, ships, and cars. It is also essential in the study of weather patterns, ocean currents, and the behavior of blood flow in the human body. Additionally, fluid mechanics is crucial in industries such as oil and gas, water treatment, and manufacturing.
