An architect-engineering firm is planning a parking lot to accommodate 500 vehicles. each parking space will be 8 feet times 13.5 feet. it has been estimated that the space required for aisles will be 85% of the space required for parking. a local paving company charges $13 per square foot for paving and a flat fee of $10 comma 200 for marking and painting the individual parking spaces. based on this information, what is the estimated cost of paving and marking this parking lot?

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

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
