PAD-60% Calculate the irrigation interval if the water consumptive use is 4.5 mm/day. Ex 4-2: The specific gravity of the soil is 1.41 percentage of water content by weight at field capacity and wilting point are 15% and 7% respectively. a) calculate the equivalent depth of moisture content for 1.2m root zone and PAD 70% at permanent wilting point, at field capacity and for readily available water b) If the crop consumptive use is 18 m/donum/day, calculate: Irrigation interval in days, field water duty assuming 40% losses during irrigation and amount of added water to irrigate one hectare. Ex4-3: Using Blaney-Criddle formula, calculate the irrigation interval through specific interval of plant growth according to the following data: . Mean air temperature 25 C percentage of day light hour through the month 8.4% Crop…

Determine the global stiffness matrix of the beam shown in Fig. 3. Assume supports at 1 and 3 are rollers and the support at 2 is a pinned support.  Indicate the degrees of freedom in all the stiffness matrices. EI is constant, w=60kN/m, L1=1.25m and L2=3.75m   please explain how the code numbers for global matrix are determined in detail

For the truss shown in Fig 2, determine the nodal displacement and member forces for all elements of the truss. Assume for each member A = 0.0015 m2 and E = 200 GPa please show all working, relevant FBD's and use ID's indicated in the diagram, if using an alpha numerical in equations please indicate where it is being applied to in the truss.
