One of your classmates claims to have invented a flow device to increase the superheat of steam. His claim is that he can feed steam at 0.15 MPa and 150°C and obtain steam at 250°C and 0.1 MPa. The device also yields water at 100°C and 0.1 MPa. The ratio of product steam to product water is 10:1. No heat or work is added to system but some heat loss may occur. a) Based of Thermodynamic considerations, does this system work? b) What kind of equipment is used in this device? c) What is the thermodynamic limit to the product steam to water ratio?
A ball is thrown vertically up with a velocity of 91 ft/sec at the edge of a 190-ft cliff. Calculate (a) the height h to which the ball rises and (b) the total time t after release for the ball to reach the bottom of the cliff.
