    Equation for work of a reversible isothermal compression

    I need to find the equation for the work of a reversible isothermal compression of 1 mol of a gas in a piston/cylinder assembly if the molar volume of the gas is given by V= ((RT)/P) + b where b and R are positive constants. Not sure what to do .. please help! THANKS

    How Does Changing Mass Flow Rate or Diameter Affect Reynolds Number?

    The question gives this .. The Reynolds number, Re, is a dimensionless group which characterizes the intensity of a flow. For large Re, a flow is turbulent; for small Re , it is laminar. For pipe flow, Re=u(density)D/mu, where D is pipe diameter and mu is dynamic viscosity. It asks ...
