A proposal has been made to use stainless-steel tubing as part of the heat-transfer system in a nuclear reactor. High temperatures and extremely high rates of heat transfer will be involved. Under these conditions, temperature stresses across the tube walls will be high, and the design engineer must choose a safe wall thickness and tube diameter for the proposed unit. List in detail all information and data necessary to determine if a proposed tube diameter and gauge number would be satisfactory.
Empirical correlation/model for onset of flooding in gas-liquid flow in horizontal pipe MatLab
Using the concepts of material balances, determine how much (in moles and lbs) air is needed and CO2, N2, CO, and H2O are emitted for every gallon of gasoline burned in your car's engine.
Sulfur dioxide produced by the combustion of sulfur in air is absorbed in water. Pure SO2 is then recovered from the solution by steam stripping. Make a preliminary design for the absorption column.
Determine the minimum number of stages required, and determine the minimum reflux ratio
High-density polyethylene may be chlorinated by inducing the random substitution of chlorine atoms for hydrogen.
What is the very largest torque T that can be applied with elastic behavior everywhere? (Hint: cut combined shaft at C and consider separate shaft). What are the supporting torques?
Compute the increase in temperature and entropy if saturated liquid water at 10 kPa is pumped to a pressure of 9.0 MPa, if the pump is 75% efficient (where 100% efficiency would be reversible). You may use constant values and at these conditions.
in heat transfer terms , the surface temperature rises above the wet bulb surface ceases to behave as a wet surface - the surface temperature rises to dry bulb temperature and air as the moisture level fa..
A 184.6-mg sample of K2Cr2O7 is dissolved in enough water to make 500.0 mL of solution. c. A 0.1025-g sample of copper metal is dissolved in 35 mL of concentrated HNO3 to form Cu2 ions and then water is added to make a total volume of 200.0 mL. (C..
At steady state with a feed concentration of 4 gmol/lit., and mean residence time of 65 sec in the second reactor, the concentration of feed to second from the first is found to be 2 gmol/lit., while that of the stream leaving the second is 1 gmol..
For the conditions indicated in Prob. 7, prepare a log-log plot of fluid velocity in feet per second versus optimum economic pipe diameter in inches. The plot should cover a fluid-velocity range of 1 to 100 ft/s and a pipe-diameter range of 1 to 1..
Acetylene (C2H2) and butane (C4H10) are gaseous fuels with enthalpies of combustion of 49.9 kJ/g and 49.5 kJ/g, respectively. Compare the energy available from the combustion of a given volume of acetylene to the combustion energy from the same ..
