A thermodynamic cycle of a gas inside a piston/cylinder assembly consists of two processes; compression and expansion. The compression process occurs at a constant temperature during which the gas pressure (P) varies with volume (V) according to the ideal gas law given as
P = a /V
where a is a constant. When the gas is left to expand, P changes non-ideally with V according to the relationship
P = b –V
where a is a constant. The two-process cycle is shown in the figure below. Determine the net work produced by the cycle.
The value of a and b are given by the instructor.
Project 4B
A cylindrical oil tank, lying on its side, is 6m long and 4m in diameter. The depth of oil in the tank is H. If the oil density is 860 kg/m3 what is the mass of oil in the tank?
Solve the problem using (a) polar coordinates and (b) Cartesian coordinates. Compare the answer in both cases.
The value of H is given by the instructor.

واعادة الترجمة بالنسبة لك ليس مشكلة كما أظن والله أعلم
