Hi,
I am doing an experiment where I am measuring the airflow readings (m/s) of different fans. I then was hoping to use this to work out the force and then from that the power to compare the efficiencies of the different fans. I was wondering if anyone had any suggestions for what equations...
It's with regards to the pressure inside the sun, P=((density)/(avg mass of a partice))*kT where the avg mass of a particle in this case is 0.5 AMU. Assuming that the sun is made up entirely of Hydrogen in this case (comes out to be 0.61AMU when taking into account helium and other heavier...
Could anyone please explain why in the book The Physics of Stars it states that the mass of ionized Hydrogen is 0.5AMU, I cannot figure out why it isn't 1.0078AMU minus the mass of an electron?
