Answer:
t=5.5 mm
Heat dissipation per unit length = 90.477 W/m
Explanation:
Given that
Diameter d = 5 mm ⇒r = 2.5 mm
Conductivity of insulated material K = 0.16 W/mK
Heat transfer coefficient = 20
When thickness reaches up to critical radius of insulation then heat dissipation will be maximum
We know that critical radius of insulation of wire is given as follow
Now by putting the values
So the thickness of insulation
t=8-2.5 mm
t=5.5 mm
As we know that heat transfer due to convection given as follows
Q = hAΔ T
Q=20 x 2 x π x 0.008 x (120-30)
Q = 90.477 W/m
So heat dissipation per unit length = 90.477 W/m
Answer:
total_cost = cost + tax
Explanation:
Step1) Let the 2 variable for take input from user e.g price and quantity
var price ;
var quantity ;
var cost ;
var tax ;
var total_cost ;
Step2) take input from user quantity of item 'A'
step3) cost = price * quantity
Step4) tax = 0.08 * cost
Step5) total_cost = cost + tax
Step6) print the total_cost
