Is the statement true or false? Velocity pressure can be converted to velocity in feet per minute using the formula: velocity fpm = square root of velocity pressure x 4005?

The statement is true because the formula given correctly relates velocity pressure to air velocity in feet per minute (FPM). When calculating air velocity, velocity pressure is an essential metric, and the formula is derived from Bernoulli’s principle, which describes fluid dynamics.

To elaborate, the velocity pressure is measured in inches of water, and the conversion factor of 4005 comes from specific calculations involving fluid properties, particularly at standard air conditions. This specific factor allows you to compute the square root of the velocity pressure, yielding the velocity in FPM. The formula effectively shows how an increase in velocity pressure correlates with an increase in airflow velocity, making it useful for engineers and technicians working in HVAC and related fields.

Options that imply the statement is false or only partially true do not take into account the accuracy and applicability of this established formula under standard assumptions regarding air density and temperature, which are typically the conditions in which this calculation is employed. Therefore, the conversion provided in the statement is indeed valid within those typical parameters.
