River models are used to study many different types of flow situations. A certain small river has an average width and depth of 65 ft and 7 ft, respectively, and carries water at a flow rate of 775 ft3 / s. A model is to be designed based on Froude number similarity so that the discharge scale is 250. At what width and flowrate would the model operate?

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
