Flow through pipes, pumps, compressors. air cooler and separator. a) water, entering at 1 bar and 25 °c, is flowing at a rate of 100 kg/h in a mild steel pipe. pipe diameter is 1 inch schedule 40. the length of the pipe is 1000 m. determine the pressure at the exit of the pipe. the pipe is horizontal.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
