목차

3.12. An ideal gas is flowing in a constant-diameter pipe at at a constant temperature. What is the relation of average velocity to pressure?

3.14* A water tank has an inflow line 1 ft in diameter and two outflow lines of 0.5ft diameter. The velocity in the inflow line is 5 ft/s. The velocity out one of the outflow lines is 7 ft/s. The mass of water in tank is not changing with time. What are the volumetric flow rate, mass flow rate and velocity in the other outflow line?

3.20. The tank in Fig. 3.7 has an inflow line with a cross-sectional area of 0.5 ft2 and an outflow line with a cross-sectional area of 0.3 ft2. What is flowing in the inflow line at velocity of 12 ft/s, and gasoline is flowing out the outflow line at a velocity of 16 ft/s. How many lbm/s of air are flow through the vent? Which way?

3.12. An ideal gas is flowing in a constant-diameter pipe at at a constant temperature. What is the relation of average velocity to pressure?

The average velocity

V_average=Q/A

V_average=m ̇/ρA

The area of pipe

A=π(d/2)^2

The ideal gas

PV=nRT

n/V=P/RT

m/MV=P/RT

ρ/M=P/RT

ρ=PM/RT

Substituting three equations
