Use Manning's equation to analyze flow in a gutter along a 6-inch high vertical curb. The longitudinal slope of the gutter is 1%, z is 24, and Manning’s n is 0.016. (a) What is the maximum discharge that the gutter can carry during a storm event without the water overtopping the curb? (b) For this case, how far does the water encroach onto the roadway? (this is the top width) (c) The maximum top width allowed for design is 9 ft (so the water fills a parking lane but does not encroach onto the travel lanes of the road). Determine the water depth and design discharge for this case. (d) Design codes often suggest using the following equation instead of Manning’s equation. Sx is the gutter cross-slope, which is 1/z. = 0.56 ( 1 nSx ) S 1/2y 8/3 Redo part (c) of this question using this alternative equation. Compare your answers. Which equation provides a more conservative design approach? Explain your answer.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
