You're analyzing flow dynamics in a test section of wind tunnel, but you're dissatisfied with the resolution of your analysis because you can't see all the small turbulent effect. in order to get a clearer idea of micro flow dynamics you decrease the gap between your grid points by a factor of 100? a. by what factor does the number of points in your test section increase? b. what phenomenon does this problem demonstrate? c. how might richardson extrapolation in this scenario?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
