Measurements of Flow Flashcards
What is flow velocity
The velocity with which a fluid is moving
What is volumetric flow rate
The volume of fluid moving along a duct in m^3/s
What is mass flow rate
The mass of fluid moving along a duct in kg/s
What is streamline or laminar flow
When flow rate of a fluid through a pipe is low
What is turbulent flow
Then the speed of flow increase and elements of the fluid start intermittently
What is head loss
The point after a Venturi where pressure drops
What are some problems with orifice plates
The discharge coefficient c is sensitive to the sharpness of the edge,
With use the edge of the orifices become rounded,
Build up of solids can occur
What is a Venturi tube used for
To measure the volumetric flow rate of a fluid in a pipe
What is a orifice plate used for
To measure variable pressure
What is a rotameter used for
To measure variable area flow
What type of flow can pitot tubes be used for
Both turbulent and laminar flow
