Problem1 True or False (10 points) 1. The pressure drop increases proportionally to the mass flowrate for a turbulent flow in a pipe.(A)O(B)X

3) With shear-thinning liquids, a turbine gives a much lower shear rate near the wall, and thus the velocity near the wall is much higher than that with a Newtonian fluid.(A)O(B)X

4) The settling of nanoparticles does not occur due to brownian movement.(A)O(B)X

5) The radial velocity decreases with the distance from the tip of a turbine blade, but the volumetric flow rate increases with the distance until the maxinum flow rate occurs.(A)O(B)X

6) The Froude number is a measure of the ratio of the inertial stress to the shear force per unit area acting on the fluid.(A)O(B)X

7) In a pseudoplastic liquid, blending times at Re ＜ 1,000 are much longer than in newtonian liquids under the same impeller conditions.(A)O(B)X

8) In the free mot otion of nonspherical particles through a fluid, the orientation is constantly changing. Thus, the effective drag on the particle is less than for the motion of the fluid past a fixed particle.(A)O(B)X

9) For an adiabatic process of airflow, the stagnation temperature is constant from the entrance to the exit of the conduit.(A)O(B)X

10) The drag coeficient of a spherical particle drops suddenly when the corresponding Reynolds number reaches 200,000.(A)O(B)X

1. In chemical dehumidification process (A)wet bulb temperature increases. (B) dry bulb temperature remains constant. (C) dew point temperature increases. (D)dry bulb temperature increases.
