Liquid water enters a valve at 150°c and 3 atm, and exhausts at 1 atm determine the exit temperature. 3. a blow dryer is rated at 1500 w and has a 1.5 in diameter outlet tube. air enters the device at 70°f and leaves at 150°f. neglecting the energy to run the fan, estimate the outlet air velocity.

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.
