Document Summary
The coefficient of volume expansion of a metal, instead of being constant, changes with temperature according to the following relation: Where a and b are constants. a += . 2bt: if the volume of a block of such metal at temperature t0 is v0, calculate the volume of the same block when the temperature is raised to a value t1>t0. Write your answer in terms of a, b, t0, v0, and t1. An apparatus to measure the speed of water is shown in the figure. It consists of a horizontal pipe with radius r1. The pipe has a constriction at the right end, open to air, with radius r2=r1/2. The pipe is connected to another vertical pipe of length l, closed at the end and filled with air. When the speed of the water out of the constriction is v2, the level of the water in the vertical pipe is h1.
