QUIZ 1 page b of 10) Pe-rtu eduph My Courses MODULE 2- PROPERTIES OF FLUID QUIZ 1 My courses HYDRAULICS Consider two tanks filled with water. The first tank is 8 m high and is stationary, while the second tank is 2 m high and is mocing upward with an acceleration of 5 m/s^2. Which of the following statement is true to the two tanks with regards to the pressure at the bottom. Justify your answer. O a. None of the above O b. Tank A has higher pressure at the botto than Tank B. O c. Tank B has higher pressure at the bottom than Tank A. O d. Tank A and Tank B has same pressure at the bottom. Next pa

Urgent, need correct answer as soon as possible with complete solution. Box final answer in 4 decimal place. Thank you A pressure gauge at elevation 8 m at the side of the tank containing a liquid reads 80 kPa. Another gauge at elevation 3 m reads 120 kPa. a. Compute for the Specific weight b. Compute for the Density c. Compute for the Specific gravity

Hi Can you help me with my assignment. Just show your solutions, and write it down properly on a paper, don't type it.

A gasoline line is connected to a pressure gauge through a double U-shaped manometer, as shown from Figure 1. a) If the gauge pressure reading is 370 kPa, determine the gauge pressure of the gasoline (kPa). b) If the gauge pressure reading is 240 kPa, determine the gauge pressure of the gasoline (kPa). c) Indicate the pressure difference between the measured pressure and the calculated pressure. Assumptions: 1 - All liquids are incompressible. 2 - The effect of the air column on the pressure is insignificant. Properties: The specific gravities (GE) or also called the relative density (DR) of the oil, mercury and gasoline are 0.79; 13.6 and 0.70; respectively. Consider the density of water ρH O = 1000 kg/m and gravity as g = 9.81 m/s². Tip: Starting with the pressure indicated by the pressure gauge and moving along the tube adding (as we go down) or subtracting (as we go up) the ρgh terms until we get to the tube of gasoline, and set the result equal to P .

Q2) a) Define the following surface tension, , pitot tube , barometer ,Reynold number b) A bourdon pressure gauge records a pressure of 100 KN/m2 .The barometer reading is 761 mm Hg, what is the absolute pressure in 1) KN/m2 2) Bar 3) mm Hg 4) pascal

Question 4 of 13 -/8 View Policies Current Attempt in Progress Three liquids that will not mix are poured into a cylindrical container. The volumes and densities of the liquids are 0.607 L, 2.60 g/cm³; 1.13 L, 1.18 g/cm3; and 0.357 L, 0.634 g/cm3. What is the force on the bottom of the container due to these liquids? One liter = 1L = 1000 cm?. (Ignore the contribution due to the atmosphere.) Number i Units I!

a) Determine the force required to just submerge a Size 5 soccer ball (assume 9" diameter) in a swimming pool. Neglect the weight of the soccer ball material & air inside. b) Determine the force required to just submerge a 3ft diameter beach ball in a swimming pool. Neglect the weight of the beach ball material & air inside. c) Do the same calculations for submerging the soccer ball and beach ball but this time in a vat filled with mercury. d) Compare the forces and explain your results.

Moving Question 37 A pressure gage 10.82 m. above the bottom of a tank containing a liquid reads 58.09 kPa; another gage at height 3.39 m. reads 83.33 kPa. Determine the density of the liquid. Round off to three decimal places. Question 37 of 48 A Moving to another question will save this response.
