A heat exchanger is to be designed to condense 1100 kg/hr of steam ay 150 kPa. For this purpose, cooling water at 50 degrees celsius is available in sufficient quantity to accomplish the cooling. You are to design a shell-ad-tube exchanger with steam in the shell and one tube pass as the condenser. Calculate the convection coefficients for condensation and forced flow through the tubes. Select several alternatives for the tube bank and tube size, determine the length of the heat exchanger, and calculate the pressure drop through the tubes for each selection. Recommend a final design that specidies water-flow rate, tube size, number of tubes, and tube length. Comment on your selection.
the coefficients of static friction and kinetic friction 0.4, 0.30 between all surface of contact. determine the force p for which motion of the 30kg block is impending if cable AB is attached is shown and removed.
find densities, enthalpies and efficiency for gas turbine power cycle with the following conditions.
In the position shown, the angular velocity and the angular acceleration of the rod AB are 4 rad/sec and 6 rad/sec2, respectively, both counterclockwise. For this instant calculate the velocity and acceleration of collar A. ( AB = 600 mm)
How do I find the factor of safety using the distortion energy failure theory?
the cable from C to D prevents the plate and shaft from turning, and the weight of the assembly is carried by hearing A.
this would provide you with a set of Reynolds numbers. Next, using the integral method, determine the velocity profiles within the boundary layer to be followed by determination of the heat transfer coefficient values for your selected Reynolds numbe..
Estimate a value for the convective coefficient, h, with the basis of your estimate and show a diagram with the energy fluxes on the pipe.
determine the expressions for attractive and repulsive energies, EA and ER as a functions of r where r is in nm and E is in eV.
The catapult is used to launch a ball such that it strikes the wall of the building at the maximum height of its trajectory. If it takes 1.5 s to travel from A to B, determine the velocity vA at which it was launched, the angle of release q, and t..
A piston-cylinder device is insulated and contains 0.005 m3 of saturated liquid water at a constant pressure of l50 kPa. An electric resistance heater inside the cylinder is now turned on, and 1800 kJ of energy is transferred to the steam.
ten kilograms of water initially at 3000 kpa 200degc are contained in a piston-cylindernbspdevice shown below. a
an fcc iron-carbon alloy initially containing 0.20 wt c is carburized at an elevated temperature and in an atmosphere
