Solve Prob. P5.49 for glycerin at 20°C, using the modi- fied sphere-drag plot of Fig. 5.11.
The sphere in Prob. P5.48 is dropped in gasoline at 20°C. Ignoring its acceleration phase, what will its terminal (constant) fall velocity be, from Fig. 5.3a?
Prob. P5.48
A smooth steel (SG= 7.86) sphere is immersed in a stream of ethanol at 20°C moving at 1.5 m/s. Estimate its drag in N from Fig. 5.3a. What stre quadruple its drag? Take D 2.5 cm.
