Answer:
Explanation:
Given data:
flow rate = 10 gallon per minute = 0.0223 ft^3/sec
diameter = 0.75 inch
we know discharge is given as
Q = VA
solve for velocity V = \frac{Q}{A}[/tex]
V = 7.27 ft/sec
we know that Reynold number
calculate the 
ratio to determine the fanning friction f
from moody diagram f value corresonding to Re and is 0.037
for horizontal pipe
where 1.94 slug/ft^3is density of water

Answer:
3.115× 
meter
Explanation:
hall-petch constant for copper is given by
=25 MPa
k=0.12 for copper
now according to hall-petch equation
= +
240=25+
D=3.115× meter
so the grain diameter using the hall-petch equation=3.115× meter
