Answer:
\epsilon = 0.028*0.3 = 0.0084
Explanation:
\frac{P_1}{\rho} + \frac{v_1^2}{2g} +z_1 +h_p - h_l =\frac{P_2}{\rho} + \frac{v_2^2}{2g} +z_2
where P_1 = P_2 = 0
V1 AND V2 =0
Z1 =0
h_P = \frac{w_p}{\rho Q}
=\frac{40}{9.8*10^3*0.2} = 20.4 m
20.4 - (f [\frac{l}{d}] +kl) \frac{v_1^2}{2g} = 10
we know thaTV =\frac{Q}{A}
V = \frac{0.2}{\pi \frac{0.3^2}{4}} =2.82 m/sec
20.4 - (f \frac{60}{0.3} +14.5) \frac{2.82^2}{2*9.81} = 10
f = 0.0560
Re =\frac{\rho v D}{\mu}
Re =\frac{10^2*2.82*0.3}{1.12*10^{-3}} =7.53*10^5
fro Re = 7.53*10^5 and f = 0.0560
\frac{\epsilon}{D] = 0.028
\epsilon = 0.028*0.3 = 0.0084
I put
People who pursue a career in the creative imaging fields have qualities like a good imagination, creativity, open minds, good with ideas, and handling situations. If you enter that field, you need imagination to create things and an open mind to be open to all creations. You need good ideas to make good thing that will work.
please don't plagiarise tho, re-word it.
My answer says there is a link but not,there isn’t so here a photo of my answer.
Answer:
def script_input():
chances = 2
while chances > 0:
global rows
global columns
global constant
rows = int(input("Enter the number of rows: "))
columns = int(input("Enter the number of columns: "))
constant = int(input("Enter the constant: "))
if rows > 0 and rows <= 8 and columns > 0 and columns <= 8 and \
isinstance(constant, int):
chances -= 2
else:
chances -= 1
script_input()
print(f"{rows} rows, {columns} columns, value of {constant}")
Explanation:
The python script defines a function that gets the user input of row, column and constant value variables, then the script prints out the number of rows and columns for the matrix to be created.
