Athick-walled, stainless steel (aisi 316) pipe of inside and outside diameters 15 mm and 40 mm is heated electrically to provide a uniform heat generation rate of 1.0 × 106 w/m3. the outer surface of the pipe is insulated, while water flows through the pipe at a rate of 0.1 kg/s. evaluate the properties of the stainless steel (aisi 316) at 400 k. assume the tube surface is smooth and use the gnielinski correlation for the nusselt number. (a) if the water inlet temperature is 20°c and the desired outlet temperature is 40°c, what is the required pipe length, in m?

Aparticle moves in a circle 1.50 m in radius . through what angle in radians does it rotate if it moves through an arc length of 2.50m? what is the angle in degrees?

Atank is filled with an ideal gas at 400 k and pressure of 1.00 atm . part a the tank is heated until the pressure of the gas in the tank doubles. what is the temperature of the gas?

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
