If the uncertainties in temperature and pressure for Prob. 7.49 are ±1.5?F and ±2 kPa, respectively, what is the uncertainty of the billing if the actual volume flow measurement is exact?

Prob. 7.49

A positive-displacement meter is used to measure the flow of methane (CH₄) at 20?F and 0.95 atm. Temperature and pressure transducers are installed that feed an electronic circuit, which then indicates the flow in standard cubic feet per minute (ft3/min) for billing a customer. The meter itself senses actual volume flow. What factor must be multiplied by the actual volume flow to give SCFM?
