Apolymeric cylinder initially experiences a stress with magnitude (absolute value) of 1.1 mpa when compressed.

after 49 days the magnitude of the stress is found to have decreased to 0.51 mpa.

determine approximately how long, in days, it will take until the magnitude of the stress reaches 1/10 (one-tenth) of its initial value?

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.
