Let's say you bought a plywood 2.5 m wide and 2 m long and placed it on the roof of your car.
The boundary layer formed when driving the car towards the house is laminar along the plate and the air flow of the plate
It is assumed that it is aligned in parallel. The boundary layer thickness at the end of the plate (escape edge) is 12.5 mm
by;
a) Local speed at the point of the plate (x, y) = (0.5 m, 2.5 mm), u
b) Local shear stress of the plate at the point (x, y) = (0,5 m, 2,5 mm), τx (Pa)
c) Find the total drag force on the plate, D (ρ air = 1.2 kg / m3, ν = 1.510-5 m2 / s).

You are asked to build a new hospital: This will be a children hospital. And It will be a digital hospital, which will use all technological facilities. This assignment will be prepared in 3 parts.
a) FIRST PART: Start with the architectural structure of the hospital. Using your creativity, build a well-designed hospital for children with colors, interior and exterior. Do not forget to draft the architectural structure you designed for homework. (Information: This section will be at least “3” pages. The first two pages will be used to discribe the design. The third page will be a draft image of hospital)
b) SECOND PART: Remember all the topics you learned in this lesson. Plan the technological applications that should be in the digital hospital you will build using this knowledges.( Information: This section will be at least “3” pages.)
c) THIRD PART: Using your creativity and modern technology, plan a communication method for pediatric patients who can be used in this hospital and also after discharge. ( Information: This section will be at least “1” page.)

3. An oil well contains water at the bottom, oil floating on it, and air above the oil. You performed
two time-of-arrival measurements with an instrument that measures the depth of the well using
a light beam. The first reading on the instrument is t1= 1.33us and the second one is
t2= 1.29 us taken after a certain amount of oil was pumped out.
Calculate the change in the oil level considering the oil refractive index 1.46.

State whether the followings are True or False? (1) The angle of internal friction can vary from 0 to 90˚ since it is an angle. (2) A degree of saturation of 40% implies that 40% of the total volume consists of water. (3) Clays can have both cohesion and angle of internal friction. (4) In the triaxial test the horizontal plane is the major principal plane. (5) Piping (failure due high exit hydraulic gradient downstream) starts upstream and then progress to downstream face of a concrete dam. (6) It is safe to say that: in general natural soils in the field have larger permeability in the horizontal direction than the vertical direction. (7) Due to consolidation ∆? ?????????,?ℎ?? ? ?????????. (8) Consolidation is process of reducing voids by removing water and air if present. (9) In seepage in two dimensional impervious boundaries are equipotential lines. (10) Lowering the ground water table will increase the shear strength of the soil. (11) Due to consolidation the effective stress will increase. (12) Increasing the water pressure head at both upstream and downstream by 1 m will reduce piping.
