DW1380 In-plane Water Flow Rate Test Apparatus is used to determine the in-plane flow rate per unit width within manufactured plane and hydraulic transmissivity of geosynthetics under varying normal compressive stresses and specified hydraulic gradients. The flow of water in the plane is ...
Learn how to use the water flow calculator with a step-by-step procedure. Get the water flow calculator available online for free only at BYJU'S.
Measuring water vapor transmission rate: By measuring the change in weight of the moisture permeable cup over time, the water vapor transmission rate of the material is calculated to evaluate its water vapor transmission performance. Control test conditions: The instrument can set test conditions such...
