Liquid flows downward in a 1 cm diameter, vertical, smooth pipe with a mean velocity of 2.0 m/s. The liquid has a density of 1000 kg/m3 and a viscosity of 0.10 Ns/m2 . If the pressure is 600 kPa at a given section, what is the pressure at a section 10 m below the previous section?

On a average work day more than work place firs are reorted

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
