How do we solve this?

Consider the air over a city (60x25 km). Wind with 18 km/hr speed brings the fresh air into
the city from the west side of the region (25 km wide). Assume that 15 kg/s carbon
monoxide (CO) is emitted from different sources in the city to the air. Assume, also, that the
CO is conservative and uniformly spread all over the area up to an altitude of one kilometer.
Modeling the air over the city as a steady-state system, find the CO concentration of the air
over the city in ppm if the temperature is −20oC and pressure is 1 atm.

So how do sailboats sail up wind? It is obvious how they move with the wind but definitely not so obvious how they go against the wind. Going along with this, baseballs would still fly even if there was no lift but how do frisbees and boomerangs work?

Assume that we wish to design a Mach 10 hypersonic wind tunnel using air as the test medium. We want the static pressure and temperature in the test stream to be that for a standard altitude of 55 km. Calculate (a) the exit-to-throat area ratio, (b) the required reservoir pressure (in atm), (c) the required reservoir temperature, and (d) the exit velocity. What do these results tell you about the special (and sometimes severe) operating requirements for a hypersonic wind...

we examined the concept of friction and how it affects everything we do. Air resistance is an important type of friction that you don’t want to forget about as you prepare your post. Consider what the world would be like without friction. For example, in a world without friction, the pitcher in a baseball game can still pitch the ball because he can push off the pitching rubber. The pitching rubber is the rubber slab atop the pitching mound that...

c) Consider a city which is locate on a long (10 km.) thin island. It has a population density of 100 people per km. which is the same everywhere in the city. Each person drinks exactly 1 cup of coffee per day and are willing to pay $5 per cup. The average cost of selling coffee is simple: the minimum average cost is $2 per cup if it sells 200 cups per day and the average cost rises by 10...

How do we solve the problem of the federal budget? Do you think you can do better than our lawmakers in Washington? Why is it so complicated? Here's your chance to take a crack at it. Use the budget simulator below to try to balance the federal budget, or at least bring it under control. Now, before you even get started, you must seriously think about a couple of things: you can't just cut programs you don't like, without thinking...
