Answer:
The Mach number is 2.866
Total temperature To = 528.524K
Explanation:


Temperature (T) = 200K
For air, r= 1.4
To find the Mach number we use:
![Po/P = [1 + (r - 1/2) M^2] ^ r^/^r^-^1](https://tex.z-dn.net/?f=%20Po%2FP%20%3D%20%5B1%20%2B%20%28r%20-%201%2F2%29%20M%5E2%5D%20%5E%20r%5E%2F%5Er%5E-%5E1%20)
![1.5 * 10^6 / 5 * 10^4 =[ 1 + (1.4 -1 /2) (M^2) ] ^ 1^.^4^/^1^.^4^-^1](https://tex.z-dn.net/?f=%201.5%20%2A%2010%5E6%20%2F%205%20%2A%2010%5E4%20%3D%5B%201%20%2B%20%281.4%20-1%20%2F2%29%20%28M%5E2%29%20%5D%20%5E%201%5E.%5E4%5E%2F%5E1%5E.%5E4%5E-%5E1%20)




1.6426 = 0.2M^2


M = 2.866
To find Total Temperature :
![To/T = (Po/P)^r^-^1^/^8) [tex][tex] To/200 = (1.5*10^6 / 5*10^4)^ 1^.^4^-^1^/^1^.^4)](https://tex.z-dn.net/?f=%20To%2FT%20%3D%20%28Po%2FP%29%5Er%5E-%5E1%5E%2F%5E8%29%20%5Btex%5D%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%5Btex%5D%20To%2F200%20%3D%20%281.5%2A10%5E6%20%2F%205%2A10%5E4%29%5E%201%5E.%5E4%5E-%5E1%5E%2F%5E1%5E.%5E4%29%20)

Answer:
τ = 0.25 lbf/in²
Explanation:
given that the oil viscosity, μ = 2.415 lb/ft-s
gap between plates = 1/4 inches = 1/4*12 = 1/48 ft
recall from newtons law of viscosity;
shear stress τ = μ du/dy =
τ = (2.415 lb/ft-s) (10 ft/s)/(1/48) ft
τ = 1159.2 lb/ft-s²
we know that, 1 slug = 32.174 lb
lb = 1/32.174 slug
∴ τ = 1159.2/32.174 slug/ft-s² = 36 slug/ft-s²
τ = 36 slug/ft-s²
multiply both the numerator and denominator by ft, this gives
τ = 36 slug-ft/ft²-s²
τ = 36 lbf/ft² where 1 slug-ft/s² = 1lbf
since 1 ft = 12 inch = 1 ft² = 12² in² = 144 in²
∴ τ = 36/144 lbf /in² = 0.25 lbf/in²
τ = 0.25 lbf/in²
