Answer:
a) See attachment
b) C = 21.626 W / m^2 .K , n = 0.593
Explanation:
a)
dT = 300 - 40 = 160 K
A = pi*D*l where D = 0.025 m
Power = P' * l = h * dT * A
P' l = h * pi * D * l* dT
Hence,
h = P' / (pi*D*dT)
We will use the above equation to compute for respective values of P'
Note: The results are tabulated and attached
b)
Assuming the dependence of the convection coefficient on the velocity to be of the form h=CV^n,
determine the parameters C and n from the results of part (a).
Taking logarithm on both sides:
Ln (h) = Ln(C) + n*Ln(V)
n = (Ln(h2) - Ln(h1)) / (Ln(V2) - Ln(V1))
n = (Ln (32.223/22.037)) / Ln(2))
n = 0.593
Using regression we can compare:
C = 21.626 W/m^2 . K
Answer:
# string_contains function is defined with input_string
# as arguments
def string_contains(input_string):
# if-statement that check if letter z is in input_string
if 'z' in input_string:
# it print"has the letter z" if it has z
print("has the letter z")
else:
# else it print "not worthwhile"
print("not worthwhile")
# string_contains function is called
string_contains("The animal is zebra")
string_contains("learning is fun")
Explanation:
The code is written in Python and well commented.
Image of the output when the function is called is attached.
Answer:
Weight(lb): 10
Flat fee(cents): 75
Cents per pound: 25
Shipping cost(cents): 325
Explanation:
we run this as a jave programming language
import java.util.Scanner;
public class Shipping Calculator {
public static void main (String [] args) {
int shipWeightPounds = 10;
int shipCostCents = 0;
final int FLAT_FEE_CENTS = 75;
final int CENTS_PER_POUND = 25;
shipCostCents = FLAT_FEE_CENTS + CENTS_PER_POUND * shipWeightPound
/* look up the solutioin above */
System.out.println("Weight(lb): " + shipWeightPounds);
System.out.println("Flat fee(cents): " + FLAT_FEE_CENTS);
System.out.println("Cents per pound: " + CENTS_PER_POUND);
System.out.println("Shipping cost(cents): " + shipCostCents);
}
}
