Question: At 17°C, a rod is exactly 18.91 cm long on a steel ruler. Both the rod and the ruler are placed in an oven at 240°C, where the rod now measures 19.18 cm on the same ruler.
Part A: What is the coefficient of thermal expansion for the material of which the rod is made? The linear expansion coefficient of steel is 11 x 10-6 1/C°
I need help to find the coefficient of thermal expansion for the material of which the rod is made.
A horizontal pipe 12.00 centimeter in diameter has a smooth reduction to a pipe 6.00 centimeter in diameter. Find at what rate does water flow through the pipes
