What are the gauge pressure and absolute pressure at a point 3 m the free surface of a liquid having a density of 1.53 x 103 kg/m3 if the Patm is 750 mm Hg? Sp gr of Hg is 13.6 and density of water is 1000 kg.m3 O 78521 N/m2 and 145090 N/m2 O 45028 N/m2 and 198453 N/m2 O 78521 N/m2 and 198453 N/m2 45028 N/m2 and 145090 N/m2

1. If in a given problem, there are N variables and M dimensions, how many repeating variables should be chosen? 2. The lift force FL on a wing is dependent on six (6) parameters: the fluid speed V, the chord length Lc, the fluid density p, the fluid viscosity , the speed of sound c in the fluid, and the angle of attack a of the wing. How many dimensionless products or tt-groups can be formed? 3. The lift force FL on a wing is dependent on six (6) parameters: the fluid speed V, the chord length Lc, the fluid density p, the fluid viscosity µ, the speed of sound c in the fluid, and the angle of attack a of the wing. Which of the following sets of variables are most appropriate to be chosen as the repeating variables? a. V, Lo, and p b. FL, V, and p c. V and p only d. V, c, and L. 4. The pipe wall shear stress Tw is dependent on the average velocity on the pipe V, the fluid density p, the fluid viscosity µ, the pipe diameter D, and roughness height ɛ along the wall of the pipe. Which of…

ASPA PLEASE

Required information Ethanol at 20°C flows at 125 U.S. gal/min through a horizontal cast-iron pipe with L=12 m and d= 6 cm. Neglect entrance effects. For ethanol, take p = 789 kg/m³ and μ = 0.0012 kg/m-s. For the given flow take Moody ≈ 0.03 and smooth 0.0176. Estimate the pressure gradient dp/dx. The pressure gradient is Pa/m.

What is the gauge pressure at point A. Write the answer using 2 significant figures (very important)

A container is filled to a depth of 18.0 cm with water. On top of the water floats a 29.0-cm-thick layer of oil with specific gravity 0.600. What is the absolute pressure at the bottom of the container? ?Pa

I didn't answer any of it I just pulled the list down so you can see the different options.
