A hair dryer is basically a duct of constant diameter in which a few layers of electric resistors are placed. A small fan pulls the air in and forces it through the resistors where it is heated. If the density of air is 1.15 kg/m3 at the inlet and 1.05 kg/m3 at the exit, determine the percent increase in the velocity of air as it flows through the hair dryer. 1.05 kg/m The increase in velocity is Pin kg/m

Water supplied to a house by a water main has a pressure of 3.3 × 105 N/m2 early on a summer day when neighborhood use is low. This pressure produces a flow of 20.5 L/min through a garden hose. Later in the day, pressure at the exit of the water main and entrance to the house drops, and a flow of only 8.2 L/min is obtained through the same hose. Part (a) What pressure is now being supplied to the house, assuming resistance is constant, in pascals? Part (b) By what percent did the flow rate in the water main increase in order to cause this decrease in delivered pressure? The pressure at the entrance of the water main is 4.9 × 105 N/m2, and the original flow rate was 210 L/min. Part (c) How many more users are there in the afternoon, assuming each would consume 20.5 L/min in the morning and 8.2 L/min in the afternoon?
In large buildings, hot water in a water tank is circulated through a loop so that the user doesn’t have to wait for all the water in long piping to drain before hot water starts coming out. A certain recirculating loop involves 40-m-long, 1.2-cm-diameter cast iron pipes with six 90° threaded smooth bends and two fully open gate valves. If the average flow velocity through the loop is 2 m/s, determine the required power input for the recirculating pump. Take the average water temperature to be 60°C and the efficiency of the pump to be 70 percent.
A garden hose with an internal diameter of 1.9 cm isconnected to a (stationary) lawn sprinkler that consists merely ofa container with 24 holes, each 0.13 cm in diameter. If the waterin the hose has a speed of 0.91 m/s, at what speed does it leave thesprinkler holes?
The flow rate of blood through a 2.00×10–6-m -radiuscapillary is 3.80×109 cm3 /s . (a) What is the speed of theblood flow? (This small speed allows time for diffusion ofmaterials to and from the blood.) (b) Assuming all the blood inthe body passes through capillaries, how many of them mustthere be to carry a total flow of 90.0 cm3 /s ? (The largenumber obtained is an overestimate, but it is still reasonable.)
A typical person begins to lose consciousness if subjected to accelerations greater than about 5g (49.0 m/s2) for more than a few seconds. Suppose a 2.40 ✕ 104 kg manned spaceship's engine has an exhaust speed of 2.60 ✕ 103 m/s. What maximum burn rate |ΔM/Δt| (in kg/s) could the engine reach before the ship's acceleration exceeded 5g and its human occupants began to lose consciousness? (Enter the magnitude.)
The pressure drop along a length of artery is 103 Pa, the radius is 9.5 mm, and the flow is laminar. The average speed of the blood is 16.5 mm/s.Randomized Variables P = 103 Par = 9.5 mms = 16.5 mm/s a. What is the net force on the blood in this section of artery in N? b. What is the power expended maintaining the flow in mW?
Oxygen reaches the veinless cornea of the eye by diffusing through its tear layer, which is 0.500-mm thick. How long does it take the average oxygen molecule to do this?
A light balloon is filled with 400 m3 of helium at atmospheric pressure. (a) At 0C, the balloon can lift a payload of what mass? (b) What If? In Table 15.1, observe that the density of hydrogen is nearly half the density of helium. What load can the balloon lift if filled with hydrogen?

A typical person begins to lose consciousness if subjected to accelerations greater than about 5g (49.0 m/s2 ) for more than a few seconds. Suppose a 3.00 x 10^4 -kg manned spaceship’s engine has an exhaust speed of 2.50 x 10^3 m/s.
