A scaffold can be used to support growth of new bone tissue for patients who have suffered an injury to part of their bone. The scaffold is placed on or near damaged bone, so that new bone tissue can grow on the scaffold and eventually connect with healthy bone. Over time, scientists have designed scaffolds using the three materials shown in the table. Material Advantage Disadvantage
metal strong can become
toxic over time
ceramic binds well with
living bone
brittle
collagen flexibile
low strength

Given the advantages and disadvantages of each material, a scientist wants to combine materials from the table to create a scaffold that will attach to the surrounding bone, is flexible, and will not cause the patient to become sick. Which materials should the scientist use in her scaffold design?

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.
