Compute isentropic efficiency of turbine and mass flow rate
A turbine produces 2 MW of power while accepting steam at 3 MPa and 400 C and rejecting steam at 50 kPa and 100C. Find (a) the isentropic efficiency of the turbine (assume no heat transfer) (b) the mass flow rate of steam.

Assume the barrel is initially at rest and that its moment of inertia can be approximated as a hollow cylinder rotating about its axis: Icylinder=MR2. Your answer should be given to a tenth of a m/s.
Let A, B, and C be independent random variables, uniformly distributed over [0,7 ], [0,8], and [0,3] respectively. What is the probability that both roots of the equation Ax^2 + Bx + C = 0 are real?
