Superimpose a uniform ?ow parallel to the x-axis of 10 m=s and a source at the origin of strength q ¼ 10p m2/s.
(a) Write the velocity potential f and stream function c.
(b) Locate any stagnation points.
(c) Sketch the body formed by the streamline that separates the source ?ow from the uniform ?ow.
(d) Locate the positive y-intercept of the body of (c).
(e) Determine the thickness of the body of (c) at x ¼ -1.
A 7.1cm external diameter, 6m long hot water pipe at 85 C is losing heat to the surrounding air at 15 C by natural convection with a heat transfer coefficient of 40 W/m2 C. Determine the rate of heat loss from the pipe by natural convection in Kw.
A four-pole, star-connected, squirrel-cage induction motor operates from a variable voltage 50 Hz three-phase supply. The following results were obtained as the supply voltage was gradually reduced with the motor running on no-load. Stator line vo..
Three kilograms of nitrogen (N2) initially at 47C and 2 bar is contained within a rigid, insulated tank. The nitrogen is stirred by a paddle wheel until its pressure doubles. Employing the ideal gas model with constant specific heat evaluated at 300K..

Knowing that the bracket AB has a uniform thickness of 5/8 in., determine the principal planes and principal stresses at point H.
a round bar is simultaneously subjected to bending moment a torsional loading and a shear loading. the maximum bending
Consider a pressure vessel constructed from Al 6063 age hardened aluminium alloy with a 3mm wall thickness, 80mm inner diameter, and 359mm length. Assume thin walled. Find the principal stresses and directions for a pressure of 3.0MPa. Calculate the ..
At steady state, air at 200 kPa, 325 K, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. The inlet cross-sectional area is 6 cm2. At the duct exit, the pressure of the air is 100 kPa and t..
if the discharge from the turbine is 250 cubic feet per second what power output may be expected from the turbine?
consider a steam power cycle in which saturated water vapor at 25 bar state 1 enters an adiabatic steam turbine. at the
Show that the spacing between (111) planes in the FCC structure is the same as the spacing (002) planes in the HCP structure. Imagine the atoms to behave as hard spheres.
steam at 5 bar 320 c enters a steady state turbine with a volumetric flow rate of 0.65m3s and evpands adiabatically to
