A 3/16 in. thick acrylic testing box with dimensions of 10 in. x 10 in. is covered with an unknown ½ in. insulation material. Determine the thermal conductivity for the insulating material if a 25W bulb is used to heat the box. The bulb maintains the inside temperature at 10ºC higher than the outside temperature. Convert all units to metric but do not include units in the answer field.

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.
