What is happening to the mass of the Sun over time? Explain
What will be an ideal response?
As 0.007 of the mass of the four protons does not end up as helium, but as energy which will then be radiated out into space, the Sun is indeed losing some mass into space over time.

Flue gases at 700ºC pass over a bank of superheater tubes at 6 m/s. The tube bank is composed of 20 columns of 2 cm diameter tubes with 40 tubes per column. The arrangement of the tubes is staggered as shown in the figure with ST = SD = 4.0 cm. Determine the pressure drop across the tube bundles, assuming that the tubes have an average surface temperature of 500ºC.
