A bridge is supported by two types of rectangular cross-section piles located in a river as shown in Figure 1. The width of the piles is w 0.5 m and their lengths are eitherl 2 m or 12 2.5 m. The river of depth of about 20 m runs at 2 m/s. Water density is ρ-1000 kg/m' and its absolute viscosityH-1 .00 x 103 N.s/m2 You are asked to perform dimensional analysis to find the drag force on the piles,...

2. (15pts) You have been asked by a baseball manufacturer to study how certain stitching patterns on a baseball prototype affect travel distance. Using principles of dynamic similarity you make a baseball model that is three times the size of a regular baseball and you place it in a wind tunnel. You remember from fluid mechanics that the Reynolds (Re) number is important to this problem (see class notes for Re number derivation) (a) What parameters must be controlled to...

3. You have been asked to investigate the feasibility of employing hot air (70 C) forced convection to produce a dried carrot stick snack food. Based on experiments, you have determined that the combined average overall heat transfer coefficient for a nominal "skinny" carrot (1.4 cm diameter, 14 cm long), when heated from 24 C in 70 C air, is 122 w/m2oK. Assume that the carrot density is 1079 kg/m3, with a specific heat of 3,790 J/kg"к, and thermal conductivity...

1-1 Suppose you want to make a scale model of a hydrogen atom. You choose, for the nucleus, a small ball bearing with a radius of 1.5 mm. The radius of the hydrogen atom is 0.529 × 10−10 m and the radius of the nucleus is 1.2 × 10−15 m. (a) What would be the radius of the model? (b) Suppose that now you want to make a scale model of the solar system using the same ball bearing as...
