The pipe Rd limitations have the same effect on the Universal Venturi Tube except that the minimum pipe Rd for the Universal Venturi Tube is 80,000, which means the flow rate can be quite a bit lower than the classical, yet still maintain the standard +/-0. It keeps the insects out of the pitot tube orifice (I just hate it when that happens). Plot results from both flow rates on the same graph. It provides more exact measurement than for example the common Pitot tube but it is intended rather for smaller flight velocities - the speed of sound is reached in the thinner part at small velocities.
