Is there a picture or something?
Explanation:
Specific cutting energy:
It the ratio of power required to cut the material to metal removal rate of material.If we take the force required to cut the material is F and velocity of cutting tool is V then cutting power will be the product of force and the cutting tool velocity.
Power P = F x V
Lets take the metal removal rate =MRR
Then the specific energy will be

If we consider that metal removal rate and cutting tool velocity is constant then when we increases the cutting force then specific energy will also increase.
Answer:
Explanation:
Given:
Diameter of aluminum wire, D = 3mm
Temperature of aluminum wire, 
Temperature of air, 
Velocity of air flow 
The film temperature is determined as:

from the table, properties of air at 1 atm pressure
At 
Thermal conductivity,
; kinematic viscosity
; Prandtl number 
The reynolds number for the flow is determined as:

sice the obtained reynolds number is less than
, the flow is said to be laminar.
The nusselt number is determined from the relation given by:
