The force necessary to compact corrugated cardboard packaging increases with the deformation of the cardboard. The voids inside the packing disappear when the deformation reaches 75%. Calculate the maximum acceleration for a package falling from a height of 1 m, if 16 mm of corrugated cardboard packaging is used and the packaging is fully compressed during impact. Assume that the strain force is directly proportional to the acceleration during strain.

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.
