Stresses exerted by brain tumors on neighboring normal brain tissue can cause serious complications. to estimate these stresses, consider a simple model for a growing brain tumor. bars constrained between the rigid sides of the skull represent the tumor (elastic modulus e1) and the brain (elastic modulus e2). at time t = 0, the lengths of the tumor and brain are l1 and l2, respectively, and the bars have equal cross-sectional areas a. l1 skull tumor brain skull l2 (a) suppose tumor growth is represented by a thermal strain t . in terms of t , compute the stress in the brain due to the growing tumor. (b) for a given t , what is the length of the tumor? (c) assume t = a(1 − exp(− where t is time and a and b are constants, and consider the following parameter values:

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.
