D1 - Fluid dynamics

• The equation for pressure is pressure = Force/area
• Absolute pressure is the relative pressure + atmospheric pressure
• Hydrostatic thrust is the force on the container.
• The equation for average pressure is density * gravity * h/2
• What is the equation for average pressure in a fluid?

  density * gravity * h/2
• What is volumetric flow rate?

  The volume that flows through a pipe per unit time
• What is the equation for volumetric flow rate?

  Volume / time or cross sectional area * velocity
• What are the equations for mass flow rate?

  Mass / time or density * volumetric flow rate
• Mass or volumetric flow rate wont change if the pipe dimensions change.
• What is the equation for the weight on an object in a fluid?

  Weight = density of object * volume of object * gravity
• What is the equation for upthrust on an object?

  Upthrust = density of fluid * volume of fluid * gravity
• What is the archimedes principle?

  The volume of fluid displaced by a submerged object equals the volume of that object, therefore the weight of fluid displaced will equal the apparent loss of weight of the object. 
• What is the equation for force using the archimedes principle?

  Force = density of object * volume of object * acceleration
