Gator Bar and Grill has decided to enclose a 330ft2 area outside their building to provide outdoor seating. The enclosed area will be a rectangle, one side of which is provided by the external wall of the building. Two sides will be made of pine board and the remaining side will be made of steel fencing material. If the pine board fencing costs $ 3 per linear foot and the steel fencing costs $ 2 per linear foot, determine the dimensions of the enclosure that will cost the least to build.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
