The viscosity of the water was 2.3×10^−5lb⋅⋅s/ft^2 and the water density was 1.94 slugs/ft^3. Estimate the drag on an 88-ft diam

eter balloon moving in air at a velocity of 3 ft/s. Assume the air to have a viscosity of 3.7×10^−7lb⋅⋅s/ft^2 and a density of 2.38×10^−3 slugs/ft^3. Also perform a dimensional analysis.

Answer:

hello your question is incomplete attached below is the complete question

answer : Drag force = 1.3 Ib

Explanation:

we have to represent the dimensions of the drag force in terms of FLT

i.e : D = f( <em>d,v,p,u </em>) represented in terms of FLT

D = F , V = LT^-1, d = L, p = FL^-4 T^2

u = FL^-2 T, Number of independent terms = 5

attached below is the detailed solution
