Tools to determine Pipe Buoyancy, External Load Design, Flow, Pricing, Rep locator, and Truckload calculator that are utilized to design and build projects using PVC pipe. All applications have an option to print the results once determined. Buoyancy Calculator The Buoyancy Calculator allows the user to determine the buoyancy force of PVC pipe during construction as well as once the pipe is installed and in use. The user chooses the pipe from drop down lists, inputs the Specific Gravity of the fluid around the pipe, the Unit Weight of the backfill material, the Concrete or Flowable Fill unit weight, and the amount of water in the pipe. Output allows the contractor to know the maximum height of each lift of Flowable fill or Concrete placed before floatation occurs, the minimum soil cover in feet with pipe empty to prevent floatation, and the Buoyancy force per foot length of pipe when empty or full of water. External Load Design This application allows the user to estimate the percent of ring deflection in buried flexible pipe utilizing the Modified Iowa Equation. This equation has been used since the late 1950’s to accurately calculate expected maximum deflections. The application follows the latest methods outlined in AWWA M23 and allows the user to choose each of the input variables based upon specific known conditions and also offers the option of selecting inputs from recommended values. Flow Calculator This calculator provides Friction loss (psi), Velocity (ft/second), and Fuel costs in dollars per hour for comparable pipe products under comparable flow conditions. It may be used to compare different diameters or different pipe products to allow the user to choose the best pipe to be used for the design as well as for life cycle costs used in value engineering of projects. Pricing The Pricing calculator allows the user to choose the PVC pipe use whether Agricultural or Utility pipe and input the Block price. The output is in dollars per foot of pipe. Find A Representative The application allows the user to choose the PVC pipe use whether for Agricultural of Utility and then choose the Nation that the pipe representative works in from a drop down list. Once a Postal Code in entered the output shows a picture and contact information for the Diamond Plastics Corporation sales representative in that area. Truckload Calculator The application allows the user to choose the nearest Diamond Plastics Corporation PVC pipe manufacturing facility from a drop down list. The user can then choose from Water, Sewer, or Ag products, the pipe type and input the quantity desired. The output will indicate the percentage of a truckload that the chosen pipe and quantity will occupy for shipment.
Buoyancy Calc
Calculate the optimal weight for scuba diving based on environmental factors. Input your weight, water type, tank, and exposure suit to get a suggested weight for neutral buoyancy.
- Calculate suggested diving weight
- Adjust for water type
- Adjust for tank type
- Adjust for exposure suit
- Supports pounds and kilograms

Quickly find out the suggested weight you should add when scuba diving in different environments. Based on PADI's Peak Performance Buoyancy basic weighting guideline*. Enter your weight in pounds or kilograms, and additionally set the type of water, tank, and exposure suit to dial in a suggested amount of weight to help keep you neutrally buoyant. *Note that this app and the developer are not officially a representative of PADI. This app will give the user a good estimate of the weight needed for the environment selected, but there are always adjustments needed to achieve peak performance, based on gender, physique, exposure suit age, accessories, etc.

Verdict
The clearest difference is review sentiment: Buoyancy Calc at 40% against DPC Tools's 0%. Buoyancy Calc also leads on ratings volume (25 vs 5). DPC Tools's advantage is rating (3.4 vs 3.1) and iOS requirement (13.0 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
DPC Tools holds the better App Store score, 3.4 against 3.1. That said, the two scores are not equally well evidenced: Buoyancy Calc has 25 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 0% of DPC Tools's written reviews are positive against 40% of Buoyancy Calc's, so the app with the better star average is not the one people write more warmly about.
DPC Tools ships an update every 2 months, Buoyancy Calc every 3 months. The most recent releases landed on September 21, 2026 and June 8, 2026 respectively.
