Answer :
Final answer:
To convert the flow rate from cfm to kg/h, we have to convert cfm to m³/s using a conversion factor, calculate the average density of the SO3/air mixture, then convert m³/s to kg/h by multiplying by the mixture's density and 3600. The given information is not sufficient for exact calculations.
Explanation:
Converting the flow rate from cubic feet per minute (cfm) to kilograms per hour (kg/h) involves several steps. First, we convert cfm to cubic meters per second (m³/s) using the conversion factor 0.00047194745. Thus, 4774 cfm = 2.25 m³/s. Next, we note that the mixture is made up of 75% SO3 and 25% air. SO3 and air have different densities, so we calculate the average density of the mixture by taking 75% of the density of SO3 and 25% of the density of air. Then, we convert m³/s to kg/h by multiplying by the density of the mixture and the conversion factor 3600. This gives us the flow rate in kg/h.However, the given question doesn't provide sufficient information about the densities of SO3 and air, so we can't calculate the exact flow rate in kg/h. Please provide the densities of SO3 and air for further assistance.
