0.09m cube of a fluid at 0.7bar are compressed reversibly to a pressure of 3.5bar according to law pvn=constant. the fluid is then heated reversibly at a constant volume until the pressure is 4bar, the specific volume is then 0.5mcube/kg a reversibly expansion according to a law pv2=constant restores the fluid to its initial state. compute the mess of the Fluid present, the value of n in the first process, and the networkdone on or by fluid in the cycle

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

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.

At 12 noon, the count in a bacteria culture was 400; at 4: 00 pm the count was 1200 let p(t) denote the bacteria cou population growth law. find: (a) an expression for the bacteria count at any time t (b) the bacteria count at 10 am. (c) the time required for the bacteria count to reach 1800.
