Refrigerant 134a flows at steady state through a horizontal tube having an inside diameter of 0.05 m. the refrigerant enters the tube with a quality of 0.3, temperature of 36°c, and velocity of 12 m/s. the refrigerant exits the tube at 9 bar as a saturated liquid. determine: (a) the mass flow rate of the refrigerant, in kg/s. (b) the velocity of the refrigerant at the exit, in m/s. (c) the rate of heat transfer, in kw, and its associated direction with respect to the refrigerant.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

not too sure thinking all accelerations are pointed down
