A concentration of 0.5 ppm by volume \(\displaystyle{S}{O}_{{{2}}}\) in the airis harmful to plant life. What is the percent by volume of thisconcentration?

Answers (1)

Concentration by volume of \(\displaystyle{S}{O}_{{{2}}}\) inair is 0.5ppm which means
0.5ppm= 0.5mg \(\displaystyle{S}{O}_{{{2}}}\) / 1.0 L air
percent by volume = volume of \(\displaystyle{S}{O}_{{{2}}}\) / volume of air *100
to calculate the volume of \(\displaystyle{S}{O}_{{{2}}}\) we need to havethe density since mass is given
V(L) =Mass(g) / Density(g/L)

The dominant form of drag experienced by vehicles (bikes, cars,planes, etc.) at operating speeds is called form drag. Itincreases quadratically with velocity (essentially because theamount of air you run into increase with v and so does the amount of force you must exert on each small volume of air). Thus
where A is the cross-sectional area of the vehicle and \(\displaystyle{C}_{{d}}\) is called the coefficient of drag.
Part A:
Consider a vehicle moving with constant velocity \(\displaystyle\vec{{{v}}}\). Find the power dissipated by form drag.
Express your answer in terms of \(\displaystyle{C}_{{d}},{A},\) and speed v.
Part B:
A certain car has an engine that provides a maximum power \(\displaystyle{P}_{{0}}\). Suppose that the maximum speed of thee car, \(\displaystyle{v}_{{0}}\), is limited by a drag force proportional to the square of the speed (as in the previous part). The car engine is now modified, so that the new power \(\displaystyle{P}_{{1}}\) is 10 percent greater than the original power (\(\displaystyle{P}_{{1}}={110}\%{P}_{{0}}\)).
Assume the following:
The top speed is limited by air drag.
The magnitude of the force of air drag at these speeds is proportional to the square of the speed.
By what percentage, \(\displaystyle{\frac{{{v}_{{1}}-{v}_{{0}}}}{{{v}_{{0}}}}}\), is the top speed of the car increased?
Express the percent increase in top speed numerically to two significant figures.

An electric heater is used to heat a room of a volume \(\displaystyle{62}{m}^{{3}}\). Air is brought into the room at \(\displaystyle{5}^{\circ}\) C and is changed completely twice per hour. Heat loss through the walls amounts to approximately 850 kcal/h. If the air is to be maintainedat \(\displaystyle{20}^{\circ}\) C, what minimum wattage must the heater have? (The specific heat of air is about 0.17 kcal/kg*Co.)
