Module 1 Flashcards
It is the branch of science which deals with the study of the behavior of fluids (gas or liquid).
Fluid Mechanics
It is any substance that can flow, either a liquid or a gas.
Fluid
It is the study of fluids at rest or equilibrium situations.
Fluid Statics
It is the study of fluids in motion.
Fluid Dynamics
It is defined as mass per unit volume.
Density (rho, ρ)
What is the formula for density?
density = mass (kg) / volume (m^3) | ρ = m/V
What is the density of water?
1.00 x 10^3 kg/m^3
What is the density of salt water?
1.03 x 10^3 kg/m^3
The _________________ of a material is the ratio of its density to the density of water (1000 kg/m^3)
Relative Density
It is the amount of force exerted on a given area.
Pressure
Its SI unit is Pascal (Pa).
Pressure
What is the formula for pressure?
pressure (Pa) = Newton (N)/area (m^2) | P = F/A
What is the formula for fluid pressure?
fluid pressure = (Pa)(g)(m)| P = ρgh
What is the force exerted on an object in water?
Fluid Pressure
The forces exerted by a fluid on the walls are _________.
Perpendicular ||
