Frial-and-error solution for heating water water is flowing inside a horizontal 나in. schedule 40 steel pipe at 37.8°c and a velocity of 1.52 m/s. steam at 1083c is condensing on the outside of the pipe wall and the steam coefficient is assumed con stant at 9100 wm2 k (a) calculate the convective coefficient h, for the water. (note that this is trial and error. a wall temperature on the inside must be assumed first.) (b) calculate the overall cocfficient u, based on the inside area and the heat- transfer flux gla, in w/m2

am i too late?

explanation:

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

since electrons are negative the answer is neagtaive

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.
