(Answered) 1 water flows at a depth of 40 cm in a 100-cm-diameter

Academics

1. Water flows at a depth of 40 cm in a 100-cm-diameter storm sewer. Calculate the flow rate and the mass flux if the average velocity is 3 m=s.

2. Air at 25-C and 240 kPa flows in a 10-cm-diameter pipe at 40 m=s. What are the flow rate and the mass flux in the pipe? (Recall that pressures are always gauge pressures unless stated otherwise.)
