Engine oil at 10◦c flows across a 15-cm-square plate upon which is imposed a constant heat flux of 10 kw/m2. determine (a) the average temperature difference, (b) the temperature difference at the trailing edge, and (c) the average heat-transfer coefficient. use the churchill relation [equation (5-51)]. u∞ =0.5 m/s.

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

Ten students stand in a circle and are told to make a transverse wave. what best describes the motion of the students? each student bumps the shoulder of his or her neighbor. at the exact time, all students take a step to the right. the students skip clockwise, going in a circular motion. one at a time, each student lifts his or her hands up and then down.
