Verify that the y component of velocity for the Blasius solution to the Prandtl boundary-layer equations is given by Eq. 9.10. Obtain an algebraic expression for the x component of the acceleration of a fluid particle in the laminar boundary layer. Plot ax versus 17 to determine the maximum x component of acceleration at a given x.

consider a medium in which the heat conduction equation is given in its simplest form as 1r2 ddrr2dtdr 1a dtdt a. is
An insulated rigid tank contains 5 kg of helium gas at 440 kPa and 31C. A valve is now opened, and helium is allowed to escape until the pressure inside drops to 200 kPa. Assuming the helium remaining inside the tank has undergone a reversible, adiab..

Using the transport theorem approach, derive the conservation of linear momentum equations. State all assumptions. Why the transport theorem is required in the context of aircraft dynamics?
A tank contains a two-phase liquid-vapor mixture of Refrigerant 134a at 10 bar. The mass of saturated liquid in the tank is 32 kg and the quality is 50%. Determine the volume of the tank, in m3, and the fraction of the total volume occupied by satura..
A researcher working on a batch of a ceramic material tested two sets of samples for fracture strength. For one set of samples the specimens were tensile bars with a 10x10x100 mm^3 tensile gauge sections, and another set were bend bars of similar siz..
Water is pumped from a lower reservoir to a higher reservoir by a pump that provides 23kW of shaft power. The free surface of the upper reservoir is 46m higher than that of the lower reservoir. If the flow rater of water is measured to be 0.03m^3/s d..
Taking the average thermal efficiency to be 34 percent, determine the amount of thermal energy rejected by the coal-fired power plants in the United States that year.
When a material is subjected to a cyclic stress, large cracks grow more slowly than small cracks. The concept of a critical stress for crack propagation is only applicable to brittle materials. Materials will not break if the applied stress is kept b..
