Ex 4-1: The field capacity and wilting point as depth equivalent of soil are
178mm and 102 mm respectively. 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%

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.

- 1) Assuming that water at 20 C is flowing through the system at a constant flow rate of 2 ft³/sec and neglecting viscous effects, calculate the EL and HGL at points A, B, and C. Sketch the EL and HGL alongside the diagram. A ZA = 55 ft D₁ = 3 in B D₂ = 6 in C 2) What is the elevation at point C in the above figure? 3) Using the figure from problem 1, sketch the EL and HGL accounting for both major and minor losses. Note that the flow rate will change due to the introduction of friction (we will explore this further in the coming weeks). You do not need to calculate the values of EL and HGL.arrow_forward8) Carbon dioxide at 20 C is transported through a pipe of 0.1 m in diameter. What is the maximum flow rate possible to achieve laminar flow?arrow_forward7) In the below diagram, the pipe diameter is 10 cm and the flow rate in the pipe is 0.3 m³/sec. At this flow rate, the pump will generate 90 m of head. The pressure at point A is 500 Pa and the water in the pipe is at 60 C. a) Taking the datum to be at the centerline of the pump, calculate the EL and HGL at points A and B, neglecting friction. b) What is the pressure at point B?
