Answer:
ω=314.15 rad/s.
0.02 s.
Explanation:
Given that
Motor speed ,N= 3000 revolutions per minute
N= 3000 RPM
The speed of the motor in rad/s given as
Now by putting the values in the above equation
ω=314.15 rad/s
Therefore the speed in rad/s will be 314.15 rad/s.
The speed in rev/sec given as
ω= 50 rev/s
It take 1 sec to cover 50 revolutions
That is why to cover 1 revolution it take
In metallurgy, non-ferrous metals are metals or alloys that do not contain iron in appreciable amounts. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight, higher conductivity, non-magnetic property or resistance to corrosion
Answer:
0.740833917 ton/hr
Explanation:
Given:
Cooling load, 8890.007 Btu/hr = 2.605 kW
Room size = 180 
According to the thumb rule
1 ton of refrigerant = 12000Btu
Hence for 8890.007 Btu/hr,
the mass flow rate of the refrigerant is =8890.007 / 12000
= 0.740833917 ton per hr
Hence, mass flow rate is 0.740833917 ton/hr
Answer:
#include<iostream>
Using namespace std;
int main()
{
int n, qty;
double price, amount;
cout<<"Number of items ";
cin>>n;
cout<<"ITEM<<"\t"<<"QUANTITY"<<"\t"<<"PRICE"<<"\t"<<"ITEM TOTAL";
for(int i= 1; I<= n; i++)
{
cin>>qty;
cin>>price;
amount = qty * price;
cout<<i<<"\t "<<qty<<"\t"<<price<<"\t"<<amount;
}
}
Explanation
The above program is written in C++ programming language
5 variables are declared and used in the program
n is declared as an integer to represent the total number of items
qty is declared as integer to represent the total quantity of each item
price is declared as double to represent the amount of each individual item
amount is declared as double to represent the total amount of an item; it is gotten by qty * price
i is declared as integer to iterated between each items
The amount of each item is calculated within the iteration and also printed immediately
