A manhole plate for a reactor is to be 2 in. thick and 18 in. in diameter. It has been proposed that the entire plate be made of stainless steel type 316. The plate will have 18 bolt holes, and part of the face will need to be machined for close gasket contact. If the base price for stainless steel type 316 in the form of industrial plates is $4.00 per pound, estimate the purchased cost for the manhole plate.
The complete combustion of acetylene, C2H2(g), produces 1300. kJ of energy per mole of acetylene consumed. How many grams of acetylene must be burned to produce enough heat to raise the temperature of 1.00 gal of water by 10.0C if the process is ..
The unit cell for Cr2O3 has hexagonal symmetry with lattice parameters a = 0.4961 nm and c = 1.360 nm. If the density of this material is 5.22 g/cm3, calculate its atomic packing factor.
It is desired to use 28.32 m 3 /min of air (metered at a pressure of 101.3 kPa and 294.1 K) in a process. This amount of air which is at rest enters the fan suction at a pressure of 741.7 mm Hg and a temperature of 366.3 K and is discharged at a pres..
Find the minimum utility requirements for this process, for a minimum approach temperature of 10 °C.
In the direct steelmaking reactor based on the reduction of an oxidizing foaming slag by char (carbon) particles and droplets of iron containing 2% carbon. Estimate the total surface area of char and iron droplets needed to achieve the smelting ..
Explain in detail the working of the instrument. Description should include neat diagram, principle of working and the source of literature.
This is a refrigeration cycle problem using propane (use p-H chart for propane in Appendix). 5.15 This problem is a Claude liquefaction process for methane. (Use methane p-H chart in Appendix). 6.2 (a, c, f, h, i) Here you are asked to express var..
The partition that divides the cylinder is removed and the contents are allowed to reach equilibrium without heat losses to the surroundings. Determine the pressure and temperature in the final state assuming steam to be an ideal-gas. Is ideality..
What is the potential difference between the starting point and the top point of the trajectory?
Reconsider the Methanol Water Distillation. If the feed stream contains 60 mol % methanol, reevaluate reflux ratio, number of stages required, and the column diameter.
A continuous filter is used to separate a clear filtrate from alumina particles in a slurry. The slurry has 30% by weight of alumina (specific gravity of alumina = 4.5). The cake retains 5% by weight of water. For a feed stream of 1000 kg/hr, determi..
A recovery of 95% of particles greater than 100 μm is required. The minimum operating temperature will be 10 °C and the maximum 30 °C. Design a hydro cyclone system to handle 1200 liters/min of this slurry.
