One-dimensional, steady flow has velocity components u = Ax, v = 0, w = 0, where A is a constant. Place yourself in the frame of reference of a particle in this flow. You observe things as a function of time t in this Lagrangian frame of reference. Supposing that u = 1 at t = 0, derive expressions for:

. the acceleration Du/Dt that you expreience

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
