Method development 25-27.

(a) explain how to measure k and resolution.

(b) state three methods for measuring im in reversed-phase chroma- tography

(c) state three methods for measuring om in hydrophilic interaction liquid chromatography.

(d) estimate tm for a 15 x 0.46 cm column containing 5-um parti- cles operating at a flow rate of 1.5 ml/min.

estimate tm if the par- ticle size were 3.5 um instead.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

An air compression refrigeration system is to have an air pressure of 100 psia in the brine tank and an allowable air temperature increase of 60°f for standard vapor compression cycle temperatures of 77 f entering the expansion cylinder and 14 f entering the compression cylinder, calculate the coefficient of performance a. 2.5 b 3.3 c. 4.0 d. 5.0
