question 1a discuss in details on five types of health effects related to exposure to hazardous substances encountered
The thermal design of a heat exchanger to recover heat from a kerosene stream by transfer to a crude oil stream was carried out in. Make a preliminary mechanical design for this exchanger. Base your design on the specification obtained from the CA..
List two reasons why water is seldom used as a solvent in sample preparation for infrared spectroscopy.
1discuss an incident fire spill explosion etc that you have experienced or research one on the internet professional
A scheme for concurrently heating separate water and air streams involves passing them through and over an array of tubes, respectively, while the tube wall is heated electrically. To enhance gas-side heat transfer, annular fins of rectangular pro..
A process modification has been devised that will increase the yield to 75%. The additional investment required is $1,250,000, and the additional operating costs are negligible. Is the modification worth making?
Consider a diatomic gas, N2, at 298 K. This gas is compressed reversibly and adiabatically from 15 dm3 to 5.0 dm3. Assume that the heat capacity of this gas is CV=5R/2, and that it behaves ideally. Calculate the final temperature, T2, of the gas.
Describe the main purpose of the Globally Harmonised System of Classification and Labelling of Chemicals - Outline the bridging principles for classification of mixtures
In a process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional sel..
Cunene is made by alkylation of benzene with propylene over zeolite catalyst. To maximize selectivity to desired products, several beds of catalyst are used inside the same reactor.
Derive an equation for the latent heat of fusion that is a function of the radius of the particle. Using this equation, for a copper particle that has a radius of 2.5 nm, find the ratio of the latent heat of fusion of the particle to the laten..
