Q1. Cement ratio for plaster
Ans. 
The cement ratio for plaster typically ranges from 1:3 to 1:6, depending on the application and surface conditions.
• A common ratio for internal plaster is 1:4 (cement:sand).

• For external plaster, a ratio of 1:6 is often used to enhance durability.

• In areas with high moisture, a 1:3 ratio may be preferred for better adhesion.

• For decorative plaster finishes, a finer sand may be used with a 1:5 ratio.

Q3. How tho calculate brick
Ans. 
Calculating the number of bricks needed involves determining the volume of the wall and the volume of a single brick.
• Measure the dimensions of the wall (length, height, thickness).

• Calculate the volume of the wall: Volume = Length x Height x Thickness.

• Determine the size of a standard brick (e.g., 190mm x 90mm x 90mm).

• Calculate the volume of a single brick: Volume = Length x Width x Height.

• Convert all measurements to the...read more

Q2. Seive analysis of aggregate.
Ans. 
Seive analysis of aggregate is a method used to determine the particle size distribution of aggregates.
• Seive analysis involves passing a sample of aggregate through a series of sieves with progressively smaller openings.

• The amount of material retained on each sieve is weighed and used to calculate the percentage of material passing through each sieve.

• The results of seive analysis are used to determine the gradation of ...read more

Q1. The depth of rice root zone is
Ans. 
The depth of rice root zone varies depending on the type of rice and soil conditions.
• The depth of rice root zone can range from 20-40 cm for shallow-rooted rice varieties to over 1 meter for deep-rooted varieties.

• The root zone depth can also be influenced by soil type, with sandy soils typically having shallower root zones compared to clay soils.

• Proper irrigation and drainage practices can help promote deeper root grow

Q2. Equation of continuity
Ans. 
Equation of continuity states that the mass flow rate of a fluid remains constant within a closed system.
• States that the mass flow rate of a fluid is constant within a closed system

• Mathematically represented as A1V1 = A2V2, where A is the cross-sectional area and V is the velocity of the fluid

• Used in fluid dynamics to analyze the flow of fluids through pipes or channels
