Q5. Why are there straight lengths important in installing a vortex orifice devices
Ans. 
Straight lengths are important in installing vortex orifice devices to ensure accurate flow measurement.
• Straight lengths help to stabilize the flow profile before it reaches the device

• They prevent turbulence and eddies that can affect the accuracy of the measurement

• The length required depends on the type of device and the flow conditions

• For example, a vortex flow meter may require 10 diameters of straight pipe upstream...read more
