Why we use potassium hydrogen pthalate for determination of calibration in Total organic carbon

Nectar Lifesciences,

While performing TOC sst analysis Zero shift disabled & sample analysis zero shift enabled why?

Where should we terminate the shield and why?

OPaL,

In a furnace, 2 chemical reactions are happening – 1 mole of solid carbon reacts with 1 mole of oxygen gas to generate 1 mole of carbon dioxide gas; 1 mole of solid carbon reacts with 0.5 mole of oxygen gas to generate 1 mole of carbon monoxide gas. In a given process, 100 kmol of carbon is burned in a furnace. (a) Calculate the theoretical oxygen gas needed by assuming that all the carbon is burned completely to carbon dioxide gas. (b) Calculate the theoretical air needed by assuming that all the carbon is burned completely to carbon dioxide gas and there is only 21 % of oxygen gas. (c) Determine the amount of air required (in kmol) if 50 % excess oxygen gas must be satisfied for (a) and (b). (d) It has latter been found that 20 % of the carbon undergoes incomplete combustion resulting to carbon monoxide gas production. The rest of the carbon undergoes complete combustion. Calculate the total oxygen gas required stoichiometrically based on the actual process.

Dear sir, my knowledge about cable size determination is limited. Though I read examples I could not calculate the Cable size required for electric driven pump 40 KW, 380 Volt, 50 HZ, 50 meter from transformer and it is three phase star delta starting. Please help as there is no one in my surroundings to help.

1.0 what is the permissible westage of steel in structural steel fabrication say gantry , trustle of power plant unit 2.0 what is the permissible westage of cement in construction work as above

PMC,

how storage location determine in delivery document please answer

Intelyst,

permissible compressive strength of m15 grade conc.

USIDCL,

why the transformer primary terminal indicated by u,v,w.to technical reason

JNTUK,

without maintaining condition record for a particular material perhaps price is determine into sales document what could be the reason

Cap Gemini,

How do you determine as to what TDS has to be deducted from each vendor supplying us the goods and doing labour work?

What is the minimum permissive IR value for LT & HT motor for safe starting?

Rukmani,

What should be the lap length in raft if height of raft is 0.800mm ...it couldn't b 50D or 40D...we just have to join upper and bottom reinforced...is there any formula for determine it...

SIPL,

A cylinder with a movable piston contains 0.1 mole of a monoatomic ideal gas. The piston moves through state a, b and c. The heat Q, changes from state c to a is 685 J. The work W, changes from state c to a is -120 J. The work, W performed from state a to b then to c is 75 J. By using the first law of thermodynamic, U = Q W where U is the internal energy : (a) Determine the change in internal energy between states a and c. (b) Is heat added or removed from the gas when the gas is taken along the path abc? (c) Calculate the heat added or removed when the gas is taken along the path abc?

What is standard receiver determination,enhanced receiver determination?
