Near the point (x, z) =(3,2) in a flow with a zero y-component (v=0), the velocity component are described by u =3x-3z, and w = 6-4z+ x. The velocities u and w are in m/s and are in the x- and z- directions, respectively. Both x and z are measured in meters and z is in the upward direction. The streamline passing through the point (3,2) is known to reach a stagnation state at the fluid surface (z=4), where the gage pressure is zero. The density of the fluid is 1000 kg/m3. Determine the velocities and u and w and the speed of the flow along the streamline at (3,2). Determine the slope of the streamline in degrees from horizontal. Determine the acceleration at the point. Determine the pressure at the point (3,2) in N/m2 gage.
Calculate the energy released per 42He nucleus produced and per mole of 42He produced. The atomic masses are 21H, 2.01410, 31H, 3.01605, and 42He, 4.00260. The masses of the electron and neutron are 5.4858 10-4 and 1.00866 amu, respectively.
