Saturated steam at 280 °C flows inside a pipe at rate of 0.02 kg / s * epsilon . Pipe ID = 5.5 cm and OD = 6 cm. Pipe is covered with 3 cm thick material which has thermal conductivity of k=0.06 W/m^ C If pipe be 30 m long, and heat transfer coefficient of steam be 15000 W/m^ 2 ^ C and heat be transferred to environment of T infty =27^ C, determine, quality of steam at exit of the pipe, as well as rate of condensation along the pipe length. For steam at 280 degrees * C . h g =2779 kJ/kg. and h_{f} = 1235 kJ/kg. Hint any assumption must verified.

Determine the wavelength of the light absorbed when an electron in a hydrogen atom makes a transition from an orbital in the n=3 level to an orbital in the n=7 level.

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
