A flow nozzle is to be inserted in a $2-$in$-$ID pipe $(2\mathrm{.}067$in$.$ ID$)$ to measure an airflow of up to $2lb\frac{m}{sec}.$

Upstream of the nozzle, the absolute air pressure is $150$ psi and the temperature is $300.$ For air $$ is

$1\mathrm{.}4.$ Pipe wall taps are to be used and the maximum pressure drop across the nozzle is to be $5$ psi $.$

What is the Reynolds numberin ${10}^5$

What is the diameter of the throat area in inch

What is the discharge coefficient value

Calculate these values $(3$ decimal places$)$ of the flow

nozzle according to ASME specifications.
