Show complete solution: Prove that for a fluid with a constant density ρ flowing at a steady-state through a straight pipe with an entry diameter of D1 and an exit diameter of D2 where D1 > D2, the difference of the velocities, i.e. v1 – v2 (velocity in – velocity out), has a negative value. Suppose that for the same system, the ratio of the velocities v1/v2 = 1/4, what is the relationship between D1 and D2?
A turbine rotates at 150 rpm and discharges 0.8 m3/s. The radial velocity at inlet Cr1 = 2 m/s and equals 6 m/s at exit. The physical data are: r1 = 0.5 m, r2 = 0.2 m, α1 = 15°, β2 = 135°, Z1 = Z2, the pressure head at exit is 6 m. Assuming a loss of head of 2 m, calculate the following: The water horsepower delivered by the turbine, (no draft tube are used) neglect circulatory flow and hydraulic losses.

A pipe equipped with a nozzle is used to deliver water to the wheel of a hy draulic turbine. The pipe has a diameter of 35 cm and a length of 1 km. The noz zle has a diameter of 10 cm and provides a velocity head of 35 m when turbine operates at steady state condition. Now, consider a case where the fully closed turbine stop valve is suddenly opened. Find the time it takes the wheel of the tur bine to reach 97% of its full speed.
Gas enters the nozzles of an axial flow turbine stage with uniform total pressure at a uniformvelocity c1 in the axial direction and leaves the nozzles at a constant flow angle α2 to theaxial direction. The absolute flow leaving the rotor c3 is completely axial at all radii. Using radialequilibrium theory and assuming no losses in total pressure show that where Um is the mean blade speed, cθm2 is the tangential velocity component at nozzle exit at themean radius r 1⁄4 rm. (Note: The approximate c3 1⁄4 c1 at r 1⁄4 rm is used to derive this expression.)
