Consider atmospheric air at 20°C and a velocity of 30 m/s flowing over both surfaces of a 1‐m‐long flat plate that is maintained at 130°C. Determine the rate of heat transfer per unit width from the plate for values of the critical Reynolds number corresponding to 105, 5 × 105, and 106.

The ph is the a.independent variable b.the dependent variable c.control group

Two solutions of the same uv-absorbing molecule were analyzed by uv-vis spectroscopy on the same instrument using 1 cm pathlength cells. use data from the table to calculate by what percentage the concentration of solution b is compared to that of solution a.sample absorbance at 315nm a 0.45 b 0.80
