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