Answer:
a)Are generally associated with factor.
Explanation:
We know that losses are two types
1.Major loss :Due to friction of pipe surface
2.Minor loss :Due to change in the direction of flow
As we know that when any hindrance is produced during the flow of fluid then it leads to generate the energy losses.If flow is along uniform diameter pipe then there will not be any loss but if any valve and fitting placed is the path of fluid flow due to this direction of fluid flow changes and it produce losses in the energy.
Lot' of experimental data tell us that loss in the energy due to valve and fitting are generally associated with K factor.These losses are given as
Answer :
The number of gold atoms in nanogram is,
The number of gold atoms in picogram is,
Explanation :
As we know that the molar mass of gold is, 196.97 g/mole. That means, 1 mole of gold has 196.97 grams of mass of gold.
As we know that,
1 mole contains number of atoms.
First we have to determine the number of gold atoms in a nanogram.
As, 196.97 grams of gold contains number of gold atoms
And, 1 grams of gold contains number of gold atoms
So, nanograms of gold contains
number of gold atoms
The number of gold atoms in nanogram is,
Now we have to determine the number of gold atoms in a picogram.
As, 196.97 grams of gold contains number of gold atoms
And, 1 grams of gold contains number of gold atoms
So, picograms of gold contains
number of gold atoms
The number of gold atoms in picogram is,
