Find the maximum density and weight of a spherical instrument package of diameter 0.5 m whose terminal velocity does not exceed 0.3 m/s when it is dropped in salt water at a constant temperature of 5°c. what are the terminal velocities if this density is in error by ±1%?

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
