find the mass flow. (b) Is the flow choked? If so, estimate A*. Also estimate (c) p, and (d) Ma1.

I need the answer as soon as possible

The potential function &, for an incompressible, 2D flow field is given by : = Ux + k ln r a) Is this flow possible? b) Determine the stream function. using polar coordinates !!

Consider the one-dimensional, incompressible flow through the circular channel shown. The velocity at section 1 is given by U5U0 1U1 sin ?t, where U0 520 m/s, U1 5 2 m/s, and ? 5 0.3 rad/s. The channel dimensions are L51 m, R1 50.2 m, and R2 50.1 m. Determine the particle acceleration at the channel exit. Plot the results as a function of time over a complete cycle. On the same plot, show the acceleration at the channel exit if the channel is constant area, rather than convergent, and explain the difference between the curves.

1.) The speed of a particle be positive or negative depending on the sense of which the particle travels along the path. True/False?

A surface condenser deals with 12000 kg of steam per hour. Air leakage into the condenser is found to be 4 kg/hr. The vacuum and temperature at the air pump suction are 700 mm of Hg and 36°C respectively. The barometric pressure is 760 mm Hg. Compute the volumetric capacity in m'/min of wet air pump.
