A square plate of size 100 cm by 100 cm is subjected to an isothermal boundary condition of 500 °C on the top and to a convection environment on all the remaining three sides of 100 ?C with a heat transfer coefficient of 10 W/m2K. The thermal conductivity of the plate is 10 W/m2K. Assume the thickness of the plate is 1 cm. Determine the temperature distribution in the plate using
(a) two triangles and
(b) eight triangles. Calculate the temperature and heat fluxes in the x and y directions at a location (x = 30 cm, y = 30 cm).
Determine the force in member CH of the truss - Determine the forces in the marked members "F2 and F1" of the truss.
A fireman is using a 10-cm inside-diameter fire hose is trying extinguish a fire. He is aiming the hose at 45° with respect to the horizontal and the water lands 30 m from the fire fighter. On the end of the fire hose is a nozzle. The inside diamete..
Carbon dioxide (CO2) gas enters a turbine operating at steady state at 50 bar, 500 K with a velocity of 50 m/s. The inlet area is 0.02 m2. At the exit, the pressure is 20 bar, the temperature is 440 K, and the velocity is 10 m/s.
The schematic of a power cycle using water flowing each component is shown. Water flows through the boiler and condenser at constant pressure and through the pump and turbine adiabatically.
measuring fracture toughnessthe aim of this demonstration is to use measurements of the load required to propagate a
Water flows at the rate of .5kg/s in a 2.5cm diameter tube having a length of 3m. A constant heat flux is imposed at the tube wall so that the tube wall temperature is 40 degrees C higher than the water temperature. Calculate the heat transfer and es..
Determine the ratios P1 : P2 : P3 of the critical loads for these columns.
If the coolant gas is air, determine the required flow rate if the heat removal rate and tube wall surface temperature remain the same. What is the outlet temperature of the air?
The desire is to raise the temperature of the ambient air from 60 degree F to 350 degrees F ---- I need to calculate the amount of steam energy in BTU's per minutes and lbs of steam per minute necessary to accomplish the increase in air temperatur..
Twenty pounds of a gas mixture is contained in a tank with volume 30 cubic feet at 30 psia and 70 F. The gas mixture has volumetric analysis of twenty percent carbon dioxide, thirty percent oxygen, and fifty percent nitrogen. Discuss how you would s..
Assume a labor rate of $50.00/hr and a burden rate of $25/hr. Assume a surface speed of 2000 ft/min. The number of teeth on the cutter is 4. The feed is 0.005 in/tooth. The depth of cut is 0.020”. The width of cut is equal to the diameter of the t..
100 grams moles of the feed with composition of 40% methane, 50% chlorine, and 10% nitrogen, are fed to the reactor every hour, the conversion of the limitining reactant is 67%. Determine which species is the limiting reactant using appropriate calcu..
