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

tester [92]

A effective ground-fault current path  is an intentionally constructed, low-impedance electrically conductive path designed and intended to carry current during ground-fault conditions from the point of grounding on a wiring system to the electrical supply source.

<h3>Is earth an effective ground fault current path?</h3>
  • Sticking the wire in the ground is not sufficient since the earth is not thought to be a reliable ground-fault current channel.
  • The electrical system of a building or other structure is based on grounding.
  • To give a fault current a secure path to travel, grounding is used.
  • When installing switches, light fixtures, appliances, and receptacles, a complete ground route must be kept.
  • The undesired current flow trips circuit breakers or blows fuses in a system that is correctly grounded.
  • Through the use of a grounding bank, effective grounding maintains voltages within predetermined limits during a line-to-ground fault (short-circuit condition).
