Students in a laboratory are studying air flowing at steady state through a horizontal insulated duct. one student group reports the measured pressure, temperature, and velocity at one location in the duct as 0.95 bar, 67oc, and 75 m/s, respectively. the group reports the following values at another location in the duct: 0.8 bar, 22oc, and 310 m/s. the group neglected to note the direction of flow on the data sheet, however. using the data provided, determine the direction of flow.
