What does feed water equivalent mean? Hurry!!

The heat capacity of an instrument is expressed in terms of water equivalent. The so-called water equivalent is the heat required to raise the calorimeter 1 in addition to water, which is equivalent to the heat capacity of the instrument with the mass of water used to absorb the same heat.

The drainage equivalent is () times the equivalent of the feed water banquet.

33 (Positive Macro Answer).

Give waterEquivalentIn simple terms, it is the amount compared to a specified value.

Definition] The rated flow rate l s of the faucet installed on the sewage basin with a branch diameter of 15mm is taken as an equivalent, and the ratio of the rated flow rate of the feed water of other sanitary appliances to it is the equivalent value of the sanitary appliance.

In order to simplify the calculation, divide the rated flow rate of the rest of the water supply appliances by the water supply equivalent. Similarly, the meaning of the discharge equivalent is the same, but the magnitude of the flow rate is different.

【**】Building water supply and drainage sales hidden project. 1 feed water equivalent: Usually the pipe diameter is 15mm, and the flow rate is Zhongxun Hall as a feed water equivalent value.

1 Drainage Equivalent: Usually the pipe diameter is 50mm, and the drainage flow rate is taken as a drainage equivalent value.

Therefore, 1 discharge equivalent is a multiple of 1 feed water equivalent.

In order to calculate a convenient definition, the so-called water equivalents are meant to be one equivalent, but two equivalents.

Based on the flow rate (feed flow or discharge flow) of a sanitary appliance, the ratio of the flow rate (feed flow or discharge flow) value of other sanitary appliances to its value is called the feed water equivalent.

1 feed water equivalent: the flow rate of a shut-off valve or distribution faucet used in the sewage basin when the outflow pressure is 20kp is fully opened as a feed water equivalent.

Water equivalent. It is also called specific heat capacity.

It refers to the amount of heat required to increase the temperature of a certain amount of homogeneous substance by 1k when there is no phase change or chemical change.

Using the concept of specific heat capacity, it is possible to deduce by analogy the molar heat capacity that represents the amount of heat required to elevate 1 mol of a substance by 1 k. And the molar heat capacity cp under isobaric conditions is called constant pressure molar heat capacity. The molar heat capacity CV under isochoric conditions is called the constant volume molar heat capacity.

The relationship between the constant pressure molar heat capacity and temperature is usually correlated as a polynomial.

Water equivalent refers to the amount of heat required to increase the temperature of a substance other than water in a calorimetry system by one degree, which is equivalent to the amount of heat required by several grams of water to rise by one degree.

To put it simply: in addition to water, the heat required for the calorimeter to rise1 is equivalent to the heat capacity of the instrument expressed by the quality of water used to absorb the same heat. For example, if the heat required to raise the instrument by 1 is 1903 J, the water equivalent of the instrument is 1903 J K.

"Equivalent" is simply a quantity compared to a specified value.

The equivalent is a dimensionless concept set for calculating the diameter of the water supply and drainage pipe of the plumbing appliance, and the water equivalent is equivalent to 5 times the rated flow value of the water supply of the sanitary appliance.

The discharge equivalent is equivalent to 3 times the rated flow rate of the sanitary appliance.

For example, if the rated flow rate of the sink sensor faucet is, then its corresponding feed water equivalent is.

The rated flow rate of the wash basin is , then its corresponding drainage equivalent is.

The rated flow rate l s of the faucet installed on the sewage basin with a branch diameter of 15mm is taken as an equivalent, and the ratio of the rated flow rate of the feed water of other sanitary appliances to it is the equivalent value of the sanitary appliance.

In the measurement of heat, the heat capacity of the calorimeter is generally referred to as the "water equivalent".

The drainage equivalent is the drainage equivalent of the sewage basin as a drainage equivalent, and the ratio of the drainage of other sanitary appliances to the drainage equivalent of the sanitary appliances.

A water equivalence is a quantity equivalent to a specified value.

is the ratio of the flow value of a sanitary appliance to the flow value of other sanitary appliances based on this base.

1 Feed Water Equivalent: A shut-off valve or faucet used in a sewage basin is used as a feed water equivalent when the outflow pressure is 20kp.

1 Drainage Equivalent: The drainage of a sewage basin is usually taken as a drainage equivalent value.

Therefore, 1 discharge equivalent is a multiple of 1 feed water equivalent.

The rated flow rate l s of the faucet installed on the sewage basin with a branch diameter of 15mm is taken as an equivalent, and the ratio of the rated flow rate of the feed water of other sanitary appliances to it is the equivalent value of the sanitary appliance.

The equivalent is a unit. 爆 zha equivalent is equivalent to how much t-n-t zha yao . It's the same thing.
