Im needed the solve max 30-45 minutes and please send Im very needed. Thank u Manufacture and design a U-pipe in an open state with a minimum of 7 different fluids with a datum. NOTE Examples of answers such as the available images and there are also problems from the 2 available images. The answer does not need to use numbers as in the example answer

A-Given that the volumetric flow rate for a fluid within a circular cross-section tube can be represented by #HAP 8pL Q where r is the tube radius, u is the fluid viscosity, P is the pressure drop across the tube, and L is the tube length, calculate the pressure drop across a tube of length 1 m and diameter of 23 mm. The fluid is blood (μ = 0.0035 N.s/m²) and has a volumetric flow rate of 4.5 L/min. Assuming the same conditions, what would the required pressure drop be for water (u= 0.001 N.s/m²) and chocolate syrup (u = 150 N.s/m²).

35 + 9.81 (0.3824 - 7-2) = - 49.54 kPa. S. Chand e oladall i.e.Pg =- 49.54 kPa. This shows that the given pressure at A, 35 kPa is gauge pressure and hence there is vacuum at point B. (Ans.) Example 6.5. An open circuit wind tunnel draws in air from the atmosphere through a well contoured nozzle. In the test section, where the flow is straight and nearly uniform, a static pressure tap is drilled into the tunnel wall. A manometer connected to the tap shows that the static pressure within the tunnel is 45 mm of water below atmosphere. Assume that air is incompressible and at pressure is 100 kPa (absolute). Calculate the velocity in the wind tunnel section (Refer to Fig. 6.6). Density of P.= 100 kPa water is 999 kg/m' and characteristic gas constant for V =0 air is 287 J/kg K. ساP حقوق النشر 25°C, Test section = 25°C (GATE)

I don't understand how they manged to divide (PA1 - PA2) by the ρwg in the image given.  I understand eveything expt for what they did with ρwghw, while combining the equations.

The clearance hole LMC diameter formula is H @ LMC = O (H +H head) / 4 O (F-F head) / 2 O (F + F head) / 2 O (F + H head) / 4

### Develop a conclusion of a piping design report for the choice of a pump, based on the calculated parameters of flow Q = 10 l/s, power of 10kw taking into account that the head of 60 mca adopted was higher than that calculated for safety, and that the pump was chosen through the WebCAPS catalogue of the company GRUNDFOS. The pump chosen was the GRUNDFOS CR 32-3 A-F-A-E-HQQE

can someone explain what has been done here ?
