4) The bottom of a corn-chips fryer is 10 ft wide and is maintained at a temperature of 420°F. Cooking oil flows across this surface at a velocity of 1 ft/s and has a free-stream temperature of 400 °F. Calculate the heat transfer to the oil and estimate the maximum boundary-layer thickness. Properties of the oil may be taken as v = 2 x 10 m²/s, k = 0.12 W/m.°C and Pr = 40.

Iimpact me by the one the yet but him.

Ithink carbon dioxide, i am not completely sure.tell me if i am wrong.

H tricky one let me think and get back to u

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
