A steam turbine operates with an inlet steam condition of $3$ MPa and $350$C and an exit steam condition of $0\mathrm{.}1$ MPa with a dryness fraction of $0\mathrm{.}95.$ Calculate the work done by the turbine per kilogram of steam, the change in enthalpy, and the change in entropy.Air flows through a converging$-$diverging nozzle with an inlet pressure of $500$ kPa, an inlet temperature of $600$ K$,$ and an inlet velocity of $100$ m$/$s$.$ The throat pressure is $300$ kPa. Calculate the throat temperature, throat velocity, and throat area assuming isentropic flow.A cylindrical steel shaft of diameter $50$ mm and length $1$ meter is subjected to a torque of $200$ Nm$.$ Calculate the shear stress in the shaft, the angle of twist in radians if the modulus of rigidity for steel is $80$ GPa, and the polar moment of inertia of the shaft.A flat plate of area $1$ m$^2$ is subjected to a uniform heat flux of $1000$ W$/$m$^2$ on one side while the other side is maintained at $25$C$.$ The thermal conductivity of the plate material is $50$ W$/$m$$K$.$ Calculate the steady$-$state temperature gradient in the plate, the heat flow rate through the plate, and the temperature at a point $10$ mm from the heated surface.A solid sphere with a diameter of $0\mathrm{.}2$ m and a thermal conductivity of $200$ W$/$m$$K is initially at a uniform temperature of $300$C$.$ It is suddenly immersed in a large body of water at $30$C with a heat transfer coefficient of $500$ W$/$m$^2$K$.$ Calculate the Biot number, the initial rate of heat transfer from the sphere, and the time required for the sphere's temperature to drop to $100$C$.$
