Answer:
Explanation:
Given that
We know that
Rex=ρvx/μ
So
All other quantities are constant only x is a variable in the above equation .so lets take all other quantities as a constant C
We also know that
Nux=hx/K
m is the constant
This is local heat transfer coefficient
The average value of h given as
---------1
The value of local heat transfer coefficient at x=L
-----------2
From 1 and 2 we can say that
Answer:
Assembler
Explanation:
An assembler can be define as a computer utility program that read, interpret and convert software programs written in low level assembly language into an object file, machine language, code and instruction that can be understood and executed by a computer.
Answer:
they work with aircraft, designing aircrafts.
Explanation:
Answer:
Outside temperature =88.03°C
Explanation:
Conductivity of air-soil from standard table
K=0.60 W/m-k
To find temperature we need to balance energy
Heat generation=Heat dissipation
Now find the value
We know that for sphere
Given that q=500 W
so
By solving that equation we get
=88.03°C
So outside temperature =88.03°C
Answer: Option A is correct -- 2.6 at% Pb and 97.4 at% Sn.
Explanation:
Option A is the only correct option -- 2.6 at% Pb and 97.4 at% Sn. While option B, which is 7.6 at% Pb and 92.4 at% Sn. and option C, which is 97.4 at% Pb and 2.6 at% Sn. and option D, which is 92.4 at% Pb and 7.6 at% Sn. are wrong.
