Electric field of the electron. The structure of the electron is not defined (that is, its dimensions cannot be identified with certainty). Its charge, however, is considered to be a point charge. Consider the following:
(a) Suppose the electron is a point charge equal to e = -1.602 x 10-19 C. Calculate the electric field intensity it produces everywhere in space.
(b) Suppose now that the charge of the electron is distributed uniformly over a spher ical volume of radius Ro = 2 x 10-13 m. Calculate the electric field intensity everywhere in space outside the electron (that is, for R > Ro). Show that the result is the same as in (a).
The compressor in a plant receives carbon dioxide at 100 kPa, 280 K at a low velocity. At the compressor exit the carbon dioxide is at 1100 kPa and 500 K with a velocity of 25 m/s. The carbon dioxide then flows into an isobaric heat exchanger where i..
air at 5 bar 500 k and a volumetric flow rate of 8 m3s enters an insulated turbine operating at steady and exits with 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. At what points on the cylinder is the fluid speed exactly equal to the ..
Steam at 3 MPa, 400C enters a turbine with a volume flow rate of 5 m^3/s. An extraction of 15% of the inlet mass flow rate exits at 600 KPa, 200C. The rest exits the turbine at 20KPa with a quality of 90% and a velocity of 20 m/s. Determine the volum..
air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine

A gantry structure, similar to a tire swing, is used to test the response of an airplane during a crash. A 8000kg plane is hoisted back until the 20m swing cable is at theta=60. Determine the speed of the plane just before crashing into the ground at..
Balls of diameters 25 mm and 20 mm were used to measure a taper ring gage. The large ball protruded mm above the end face of ring gear while the distance of the end face from the top of the 20 mm diameter ball was 40 mm.
Determine the damping ratio if the peak to peak amplitude of an accelerometer attached to a vibrating beam goes from 5V to 3V after 6 cycles of oscillation.
