Problem 8.31

To cool a summer home without using a vaporcompression refrigeration cycle, air is routed through a plastic pipe (k 0.15 W/m K, Di 0.15 m, Do 0.17 m) that is submerged in an adjoining body of water. The water temperature is nominally at T 17 C, and a convection coefficient of ho 1500 W/m2 K is maintained at the outer surface of the pipe. If air from the home enters the pipe at a temperature of Tm,i 29 C and a volumetric flow rate of i 0.025 m3 /s, Pl what pipe length L is needed to provide a discharge temperature of Tm,o 21 C? What is the fan power required to move the air through this length of pipe if its inner surface is smooth?

Lecture 11: February 16, 2016 Resilience  The ability to maintain normal services and lives after a major event.  If disruption occurs, rapid recovery with minimal social disruption.  Final state of affairs are better or as good as before the event.  Identify vulnerable facilities/systems. Earthquake Early Warning depends on info from the p-Wave. Seismic waves travel _______ in liquids than in solids. o S-waves don’t travel through liquid. Refraction happens when a seismic wave bends as it travels from one kind of material to the other. The division between the liquid outer core and the solid inner core is determined by: o The geotherm and the melting temperature of the core material. Lecture 12: February 18, 2016 Intraplate Earthquakes – earthquakes that appear away from plate boundaries. o Adirondacks o New Madrid o Eastern Canada  Intraplate earthquakes may preferentially occur along weak zones, such as former fault zones.  Intraplate earthquakes may be linked to: o Glacial Isostatic Adjustment o Sediment Erosion o Human Activity  Intraplate earthquakes have the same type of seismic hazards as interpolate earthquakes. Interplate Earthquakes – earthquakes that appear on plate boundaries. Stress Loading  Regional Tectonics  Density Contrasts  Local Topography  Intersection of Faults Induced Seismicity  Dams/Reservoirs  Hydraulic Fracturing  Waste Water Reinjection Earthquakes linked to hydraulic fracturing may cause changes in pore pressure.
