There is a double tube exchanger, in which you have glycerin flowing in the inner tube at a rate of 2.5 Kg / s, it enters at a temperature of 600 ° C and it exits at a temperature of 100 ° C, and from the outside you have water which enters at a temperature of 20 ° C, at a rate of 1.0 Kg / s, if the resistance to total heat flow is 150 KW/m^2*K, determine the value of the conduction coefficient of the pipe, if the inner pipe it is nominal 1 1/2 "Schedule 80, and the outer piping is nominal 2" Schedule 80. The system is in parallel with flows large enough to neglect convection.

What is limiting reactant? with examples

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point
