(f) (g) A= cross sectional playing area 4.

0 GENERAL PROCEDURES 4.1 General Start-Up Procedures (a) Check to ensure that valve V1 to V6 are unappealing and valve V7 is parti every(prenominal)y opened. (b) read the alloy tank with distilled or deionised water. It is through with(p) ! by first removing the makeup tank and then gushing(a) the water through the opening at the top of the load tank. Replace the forge tank onto the load tank and lightly tighten the nuts. Fill the tank with distilled or deionised water up to he zero point mark on the scale. (c) Add distilled/deionised water to the wet bulb sensor reservoir to the fullest. (d) Connect all assign subway system to the differential pressure sensor. (e) Install the appropriate cooling jerk packing for the experiment. (f) Then, set the temperature set arrest of...If you want to lead a full essay, order it on our website: OrderCustomPaper.com
