a) Assuming ideal flow, use the method of separation of variables in polar coordinates to find the stream function for uniform flow at speed U? over a circular cylinder of radius R.
b) At what points on the cylinder is the fluid speed exactly equal to the free-stream speed?
air within a gas-piston assembly and initially at stp 1atm 300k undergoes a thermodynamic cycle consisting of the
determine the force exerted by each cylinder in raising the crate for u = 60°, a 5 0.70 m, and L = 3.20 m. Show that the result obtained is independent of the distance d.
Briefly explain the difference between fatigue striations and beachmarks in terms of both size and origin.
If the chest is completely filled with ice, calculate the time for the ice to completely melt. State your assumptions. The enthalpy of fusion for water is 330 kJ/kg.
Consider a pump that discharges a liquid into a cylindrical drum at the rate of 0.064 m 3 /s. The cylindrical drum is 3.00 m in diameter and 8.20 m in depth and it can hold 40,000 kg of the liquid. Find the specific volume, density of the liquid, and..
A 2 cm horizontal jet of water with a velocity of 15 m/s is spraying onto a vertical plate attached to a cart moving opposite the direction of the water jet at 8 m/s. Determine the force required to keep the cart moving at a constant velocity.
an overall balance around part of a plant involves three inlets and two outlets which only contain water. all streams
A heat engine rejects heat to the atmosphere. The temperature of the atmosphere is 80 F. Saturated liquid water enters the boiler at a rate of 1000 lbm/hour with pressure of 250 psia. The water exits the boiler as a saturated vapor at the same pressu..
A piston cylinder device initially contains 0.15-kg steam at 3.5 MPa, superheated by 5 C. Now the steam loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. the ..
consider a metal single crystal oriented such that the normal to the slip plane and the slip direction are at angles of
a tensile force of 4200 lbs is applied to a 9 feet long 8515 brass rod. an elongation of 0.36 inch is measured on the
the metal rhodium has a fcc crystal structure. if the angle of diffraction for the 311 set of planes occurs at 36.12deg
