Question

We jump ahead to modern times and find Lazydog having lunch at Shoney's. While pounding down a BBQ bacon cheeseburger (only 1470 calories and 49 fat grams), the good professor worked on the following problems. Grab yourself an 875 calorie Ultimate Hot Fudge Cake from Shoney's and help the prestigious professor solve these problems.

This leads him to decide to calculate the terminal velocity in water of a 4.2 cm A: 76.8m/s diameter ball that has a specific C: 76.91 gravity of 1.08. Assume the viscosity m/s of water is 1.0x10-3 Pa.s. What do you calculate as the terminal velocity of this ball in water? (include units with answer) The distinguished Lazydog now decides to calculate how long it would take to drain a 2.1 ft wide by 5.0 ft long bathtub from full to half 8s full. The initial height of the water in Format Check the tub is 2.7 ft and the water goes out a 2.7 inch diameter drain in the bottom of the tub. (include units with answer) The celebrated Lazydog has recently added a 92 m3 workshop on to his house. What diameter must a 15 m long air duct have if the heating and air conditioning system is to replenish the air in the room every Format Check 20 minutes? The pump can exert a change in gage pressure of 0.65x10-3 atm. The viscosity of air is 0.018x10-3 Pa.s.
