You are working in a lab and are tasked with determining the percent plant available water for a particular soil sample. You take a field soil sample. The mass of your sample was 152g and it had 18.3% moisture by mass. Then, you place the soil sample in your pressure plate extractor and determine that the soil sample weighs 164.2g when the moisture potential is -33kPa and 130.7g at -1500kPa. What is the percent plant available moisture by mass of this soil sample? Please answer to one decimal place.
I) Two aggregates (Al and A2) were obtained from the field. A sieve analysis was performed on each sample, and the samples (originally 500g in mass) were brought to the oven dry condition (OD) and weighed. Data was obtained for each of the aggregates and is presented in the tables below. (Density of water-1g/cm) Table 1. Results from sieve analysis.

The Professor demonstrated the proper application of the procedure by analyzing a 50 mL sample of water from a local lake (Rivers Parkway) via titration with a standard solution of EDTA 0.0100 +0.0001 M standard. This sample consumed 5.00 mL to reach the Total Hardness (TH) end point; therefore, the TH of the lake was determined to be XX ± YY mg/L as CaCO,.
Read the question carefully and give me right solution. Provide detailed solution with clear calculations. The hydraulic conductivity of a soil sample, measured at 25C, was 0.005 cm/s using water as the test fluid (density = 997.2 [kg m–3 ], viscosity = 0.0008872 [kg m–1 s –1 ]. Determine the conductivity for ethanol at 10C, density = 798 [kg m–3 ], viscosity = 0.001394 [kg m– 1 s –1 ]
