You are designing a corrugated steel (n = 0.022) storm drain for a new parking lot. The topographic conditions at the site restrict the slope to be approximately 0.02 (with up to10 percent variation allowed). The storm drain needs to convey a design flowrate of 27 cfs. (a) Which size pipe and what slope would you specify? (b) What is the maximum flowrate (when full) that the pipe you specified in (a) can convey? (c) What is the velocity of the water when flowing full and at the design flowrate? (two answers) (d) Determine the depth of flow when the discharge is 10 cfs in the pipe you selected in part (a). Use the graphs on the second page of the document named "print for class on 4-3". Annotate them to show how you used them. Submit the annotated graphs. If you have access to a printer it is likely easiest to just print out the graphs and annotate them by hand. If you do not have a printer, paste the images into a program that lets you annotate by drawing lines and adding text, then save those annotated images as part of your pdf upload

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

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?
