The viscosity of a fluid is to be measured by a viscometer constructed of two 60-cm-long concentric cylinders. the outer diameter of the inner cylinder is 15 cm, and the gap between the two cylinders is 1 mm. the inner cylinder is rotated at 300 rpm, and the torque is measured to be 0.8 n·m. determine the viscosity of the fluid.

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2
