When the J and K inputs of a JKFF are tied to logic 1, this device is known as a divide-by-2 counter. Complete the timing diagram shown in Figure P6.1.49 for this counter.
Isophthalic acid (IPA, formula HOOC-C6H4-COOH) is made by oxidation of m-xylene with air. The reaction is carried out in acetic acid solvent at about 200 °C using a cobalt-manganese catalyst promoted by bromine.
A feed to a column has the composition given in the table below, and is at a pressure of 14 bar and a temperature of 60 °C. Calculate the flow and composition of the liquid and vapor phases. Equilibrium data can be taken from De Priester charts (D..
Mass transfer coefficient from a free water surface to an adjacent moving air stream has been found to be 0.015 kg/m2-s. Estimate the rate of evaporation from a surface of 1 m2 at a temperature of 28 oc into an air..
Calculate the molar mass of a gas if 2.50 grams occupies 0.0875 liters at 685 torr and 35 degrees Celsius.
The percent of the original investment paid off in the first half of the service life using the sum-of-the-years-digits method.
Explain Non-adiabatic operations of flow reactors. 15In non-adiabatic operations, heat interchange with the surroundings will beaccounted. The conversion can be defined as the ratio of the net heat still needed after heattransfer to raise the feed..
The laboratory division of your company has sent you the following data for the system n-pentane (1) propionaldehyde (2) at 35 °C: The activity coefficients of the two components at infinite dilution are 4.0 and the saturation pressures of the pur..
Use the truncated virial equation along with the second virial coefficient calculated above to estimate the volume of water at 200 °C, 14 bar. How does this value compare with the volume obtained from the steam tables? Discuss this comparison.
