Chapter 23, Problem 79P
Water in an irrigation ditch of width w = 3.22 m and depth d = 1.04 m flows with a speed of 0.207 m/s. The mass flux of the flowing water through an imaginary surface is the product of the water’s density (1000 kg/m3) and its volume flux through that surface. Find the mass flux through the following imaginary surfaces: (a) a surface of area wd, entirely in the water, perpendicular to the flow; (b) a surface with area 3wd/2, of which wd is in the water, perpendicular to the flow; (c) a surface of area wd/2, entirely in the water, perpendicular to the flow; (d) a surface of area wd, half in the water and half out, perpendicular to the flow; (e) a surface of area wd, entirely in the water, with its normal 34.0° from the direction of flow.

A rain gauge consists of a funnel with a diameter D = 10 cm that collects rain and deposits liquid water of density ρ = 1 × 103 kg / m^3 inside a cylinder of diameter d = 1 cm. The column of collected liquid rises at the rate of one centimeter per minute.
a) If the raindrops fall into the funnel with a velocity of 10 m / s, calculate the mass of water liquid in a cubic meter of the atmosphere.
b) Assuming that the raindrops have a radius of 1 mm, determine the number of drops in a cubic meter of the atmosphere. Justify your calculation method.
The average human has a density of 945 kg/m³ after inhaling and 1020 kg/m³ after exhaling.

Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at
least four-digit accuracy to minimize roundoff error.%
