Steam with a pressure of 6 MPa and a temperature of 400oC is created in a boiler at a flow rate of 0.406 m3/sec and then transported through a turbine, where it forms a saturated vapour with a pressure of 60kPa. The turbine loses 61 kJ/kg of heat to the surrounding environment at 37oC. Obtain: a) The turbine's output power.b) The highest amount of energy that can be generated.c) The turbine's second law efficiency.d) The irreversibility of the process.

2. A spherical tank with radius R (-1.5 m) has a hole at the bottom through which water drains out. The flow rate, Q, through the hole is estimated as Q=0.55m² √2gh where r is the hole radius (=0.015 m), g is the gravity constant (=9.81 m/s²), and h is the depth of water. R For the spherical tank, the volume of water, V, is given by V= h h² (3R-h) 3 The initial height of water -Q using Explicit Euler's method (A/= 200 sec), 4th dV is 2.95 m. Solve the mass balance equation H di order Runge-Kutta method (A = 200 sec), and ode45 solver. Plot water height (h) vs. time (r) for each At for 0≤t≤5000 sec and confirm that the 4th order RK method is more accurate than Explicit Euler method (we regard the ode45 solution as the true solution). Use ExplicitEuler.m and rk4.m files. Solve the same problem also using Simulink.
