A 1 cm diameter tube extends 27 cm horizontally through a region of saturated steam at 1 atm.
The outside of the tube can be maintained at any temperature between 50?C and 150?C. Plot the total heat transfer as a function of tube temperature.
A hammer head H having a weight of 0.31 lb is moving vertically downward at 40ft/s when it strides the head of a nail with negligible mass and drives it into a block of wood. find the impulse on the nail if it is assumed that the grip at A is loose, ..
A stream of gas flowing at 15,000 scfm contains 20 ppm of toluene. Assuming the process operates 8500 hours per year, calculate the potential emissions of toluene, tons/year. What kind of a system should be considered to control this stream, and why?
Determine the maximum height h which the knob may have without causing the unit to be unstable in the upright position shown. Both parts are made from the same material.
methane at 1 mpa 300 k is throttled through a valve to 100 kpa. assume no change in kinetic energy and ideal gas
a steel rod of 4m length is attached at both ends at 30 degree c. the coeff of thermal expansion is 11 10-6 and moe
water flows in a horizontal pipe with entrance velocity 2.5ms is turning 90 degrees and leaves the pipe. pipe diameter
Steam expands isentropically through a converging nozzle operating at steady state from a large tank at 1.83 bar, 2808C. The mass flow rate is 2 kg/s, the flow is choked, and the exit plane pressure is 1 bar. Determine the diameter of the nozzle,..
Determine the change in internal energy twice for each of the 3 cases identified below. In your first calculation assume ideal gas behavior, and use appropriate specific heat at the average temperature. In your second calculation, use real substance ..
The velocity profile for a film of liquid flowing down a vertical wall is given by. Where L is the thickness of the film, u is the downward velocity, xis the distance perpendicular to the wall and are the liquid density and viscosity. Sketch the velo..
although the hume-rothery rules apply strictly only to metals the concept of similarity of cations corresponds to the
Experimentally determine the measurement resolution for each range and compare it to the expected theoretical resolution. Analyze the various sources of measurement error in your system.
Derive a formula for the allowable bending moment M that can be carried by the beam based upon an allowable stress #s in the steel. (Assume that the moduli of elasticity for the steel and brass are Es and Eb, respectively.)
