A falling-head permeability test was performed on a soil sample 97-mm in diameter and 20-mm long. The stand pipe had an inside diameter of 6.0 mm. The water level in the bath surrounding the sample was 120 mm above the laboratory counter top and the water level in the standpipe fell from a height of 510 mm to 261 mm above the counter top in 46 hours and 35 minutes. Compute the hydraulic conductivity of the soil sample. Does the result seem reasonable

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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
