Water Calcium Hardness Calculator

Online Calcium Carbonate CaCO3, Water Hardness Calculation. This calculator is used to find Hardness of salts in a water. Hardness is the measure of dissolved salts in alkaline water. To measure hardness, a water operator needs to know how many mL of ethylenediaminetetraacetic acid (EDTA) it would take to neutralize the salts. This allows you to determine how much hardness was neutralized. Hardness is also measured in mg/L of equivalent calcium carbonate.

Formula: Hardness (mg/L as CaCO₃) = (mL of EDTA X 1,000)/mL of sample

Enter EDTA Value  : mL

Enter Sample Value : mL

Hardness  : mg/L as CaCO3

Where,

• EDTA : Ethylenediaminetetraacetic acid

Example: A 100 mL sample is titrated with 0.02 M EDTA. The endpoint is reached when 18.2 mL of EDTA have been added. What is the hardness concentration?
 Hardness (mg/L as CaCO3) = mL of EDTA X 1,000/mL of sample
                                            = (18.2 X 1,000) / (100)
                                            = 182 mg/L as CaCO3

Logic Gate Value Calculator

Binary Logic Gate Calculator Online. Binary Boolean Value Logic Gate Calculator is used to calculate the Boolean Expression (Logic gates) output value (True or False) for OR, AND, NOT, NOR, NAND, EX-OR and EX-NOR Gates Online. A standard Boolean value Expression(Logic gates) process signals which represent true(1) or false(2).

A truth table is a good way to show the function of a Logic Gate. It shows the output states for every possible combination of input states. The symbols 0 (false) and 1 (true) are usually used in truth tables.

The four possible combinations for a two-input gate are given as,

• Input Combination 1. "OFF", "OFF" or ( 0,0 )
• Input Combination 2. "OFF", "ON" or ( 0,1 )
• Input Combination 3. "ON", "OFF" or ( 1,0 )
• Input Combination 4. "ON", "ON" or ( 1,1 )

OR Gate:-

The output Q is true if input A OR input B is true, or both inputs are true.

                                                                    Q = A OR B

AND Gate:-
The output Q is true if input A AND input B are both true.

Q = A AND B

NOT Gate:-
The output Q is true when the input A is NOT true, the output is the inverse of the input.

                                                                     Q = NOT A

NOR Gate:-

This is an OR gate with the output inverted, as shown by the 'o' on the output. The output Q is true if NOT inputs A OR B are true.

Q = NOT (A OR B)

NAND Gate:-

This is an AND gate with the output inverted, as shown by the 'o' on the output. The output is true if input A AND input B are NOT both true.

Q = NOT (A AND B)

 

EX-OR(EXclusive-OR) Gate:-

The output Q is true if either input A is true OR input B is true, but not when both of them are true. This is like an OR gate but excluding both inputs being true. The output is true if inputs A and B are Different.

Q = (A AND NOT B) OR (B AND NOT A)

EX-NOR(EXclusive-NOR) Gate:-

This is an EX-OR gate with the output inverted, as shown by the 'o' on the output. The output Q is true if inputs A and B are the SAME (both true or both false).

Q = (A AND B) OR (NOT A AND NOT B)
