You are an engineer in an electric-generation station. You know that flames in the boiler reach a temp of 1200 K and that cooling water at 300 K is available from a nearby river. What is the max efficiency your plant will achieve?
A block-spring system oscillates with an amplitude of 3.40 cm. The spring constant is 250 N/m and the mass of the block is 0.800 kg. (a) Determine the mechanical energy of the system.
The breaking strength X [kg] of a certain type of plastic block is normally distributed with a mean of 1500 kg and a standard deviation of 50 kg.
The thermal conductivity parallel to continuous reinforcing fibers in a composite with E-glass in a matrix of polyester is found to be 0.65 W/m.K. The thermal conductivity of E-glass is 0.97 W/m.K and that of the polyester is 0.17 W/m.K.
