How do you calculate the weight of one inch deep of water on a roof covering an area of 20 feet by 20 feet?
Twenty feet times twenty feet = 400 Square feet of area. Divide by 12 to get the number of cubic feet which is 33.33. One cubic foot of water is 7.4805 gallons. One gallon of water weights 8.3249 pounds. So multiply 33.333 by 7.4805 = 249.35 gallons times 8.3249 pounds per gallon = 2075.81 pounds of water on the roof.

How do you calculate psi to move a given weight?
To calculate the psi needed to lift a weight, you would need to know the weight being lifted and the surface area over which the weight is distributed. You can then use the formula: psi = (weight / surface area). Make sure that the units of weight and surface area are consistent, such as pounds for weight and square inches for surface area.
What is the equation to calculate water depth?
The equation to calculate water depth is: [ Water Depth = Volume of Water / Surface Area of Water ]
How do you calculate the weight of coating?
To calculate the weight of coating, you need to know the area to be coated, the density of the coating material, and the desired thickness of the coating. The formula commonly used is: Weight = Area x Density x Thickness. Multiply the area by the density of the coating material and the desired thickness to determine the weight of the coating needed.
How can I calculate water pressure in a closed system?
To calculate water pressure in a closed system, you can use the formula: Pressure Force/Area. This means that pressure is equal to the force exerted on the water divided by the area over which the force is applied. By knowing the force and the area, you can calculate the water pressure in the closed system.

How do you calculate gsm of polyethylene?
To calculate the GSM (grams per square meter) of polyethylene, you need to know the weight in grams of a known area of the material. Measure a specific area of the polyethylene sample, weigh it in grams, and then divide the weight by the area measured to determine the GSM. The formula for calculating GSM is GSM = (Weight in grams / Area in square meters).

How do you calculate the weight of ISA 50x50x6mm angle?
To calculate the weight of an ISA 50x50x6mm angle, you can use the formula: Weight = Area x Length x Density. First, calculate the cross-sectional area of the angle (50x6 = 300 square mm), then convert it to square meters. Multiply the area by the length of the angle in meters and the density of the material (e.g., mild steel density is approximately 7850 kg/m^3) to determine the weight in kilograms.
How can you calculate the fabric weight in jeans?
Fabric weight in jeans is typically calculated in ounces per square yard (oz/sq yd) or grams per square meter (gsm). To calculate fabric weight, you need to know the area of the fabric (square yards or square meters) and the weight of the fabric in ounces or grams. The formula for calculating fabric weight is: Fabric weight = (weight of fabric / area of fabric).
