    Thermodynamics (Ideal Rankine Cycle)

    1. An ideal reheat Rankine cycle operates between the pressure limits of 10 KPa and 8 MPa, with reheat occurring at 4 MPa. The temperature of steam at the inlets of both turbines is 500C, and the enthalpy of steam is 3185 KJ/kg at the exit of the high-pressure turbine, and 2247 KJ/kg at the exit...

    P-N Scattering

    http://img530.imageshack.us/img530/7629/pnxl1.gif [Broken] A particle p traveling with a speed of vpi = 3 m/s hits and scatters elastically from another particle N, initially at rest. Particle p is deflected through 90°, leaving with a speed of vpf = 2.7 m/s, and a mass mp = 2 kg. a) What...

    Two Masses on Vertical Spring

    http://img158.imageshack.us/img158/6946/blockspringcy2.gif [Broken] A block of mass 10 kg hangs on a spring. When a second block with an identical mass of 10 kg is tied to the first, the spring stretches an additional ho = 1.3 m. a) What is the value of the spring constant k? Now the...
