Consider the water flow rate measurement in a pipe with the interior diameter of D_p
= 60 mm, using the orifice plate. The flow rates to be measured range from 0 m³/h to 3.6 m³/h. The available differential pressure transmitter has the measuring domain ranging from 0 mmH₂O to 2000 mmH₂O. Design the diameter of the orifice plate so as to be properly used for the given domains of the flow rate and the transmitter differential pressure. The pressure drop coefficients are given in Table 7.4.
