Flow is Inviscid: Implications on Airfoil Flow, Drag & Stall
Inviscid means flow of a fluid that is assumed to have no viscosity (i.e no firction forces). Try this website; http://www.centennialofflight.gov/essay/Theories_of_Flight/Skin_Friction/TH11.htm If we assume drag is skin-fiction drag then the effects of a real fluid flow are the result...- shinobiazra

Differential equations - finding solution
Select the correct solution for dy/dx = 1/[(4y)*(x^3)] a) x^4 b) x^(-1/4) c) 1/(x^4) d) x root 4 Choice D means instead of cubic root, to the power 4 root Plz explain how to do this. I tried separating variables and integrating the choices but it didn't work. Mayb I should...- shinobiazra

Population curve and calculations
Suppose rabbit populations grow exponentially with a growth rate of 20% per year. If P(t) is the population at any time t and 1000 is the initial (t=0) population of rabbits, what is the population of rabbits in 10 years? Use the DE model: P ' = kP with k = .1 and P(0) = 1000. Plz help me- shinobiazra

Differential equations - finding constants
Find values of the constants a and k so that y(x) = ax^k solves the differential equation; (dy/dx)^2 + [(3y^2)/(x^2)] + [(2y)/(x^4)] I tried substituiting ax^k into the DE but it did not work. I need to separate x and y but I cannot do it then I need to integrate it I think. I just...- shinobiazra
