Answer to Problem 8.102P

Impact point without spin:

Δximpact1250ft

Explanation of Solution

Given:

Golf ball diameter, D=1.7in

Inlet velocity, V0=250ft/s

Upward angle, θ0=20

For sea − level air,

Take ρ=0.00238slug/ft3

If drag and spin is neglected, we will use classical particle physics to predict the distance traveled:

Fluid Mechanics, Chapter 8, Problem 8.102P

When,

t=V0sinθg

x=Vox(2t)=V02g.2sinθ0cosθ

Substitute the given values,

Δximpact=(250)232.2sin20cos201250ft.

Answer to Problem 8.102P

Impact point:

Δximpact1570ft

Explanation of Solution

Given:

Golf ball diameter, D=1.7in

Inlet velocity, V0=250ft/s

Upward angle, θ0=20

Estimate the lift of spinning ball:

ω=7500(2π60)=785rads ;

ωRU=785(1.724)2500.22

CL=0.02

Average lift:

LCL(ρ2)V2πR2

L(0.02)(0.002382)(250)2π(1.724)20.0231lbf

Equations of motion in z and x directions and average values to be assumed:

mx¨=Lsinθ

With

θavg.10

x¨avg0.0230.10232.2sin101.3fts2

Then

xVoxt12x¨avg.t2

Where,

t=2x (time to reach the peak)

mz¨=LcosθW

Or:

z¨avg.32.20.10232.2cos1032.225fts2

Using these crude estimates, the travel distance is estimated:

tpeak=Vozaz=250sin20253.4s

timpact=2.tpeak=6.8s

Δximpact=Vox12axt2

Δximpact=250cos20(6.8)1.32(6.8)21570ft

These are 400 − yard to 500 − yard drives.

So, it would be nice, at least during teeing off, to have zero viscous drag.
