- A weather reports indicates the barometers pressure is 28.54 inches of mercury. What is the atmospheric pressure in pounds per inch?If the barometer is installed in direct sunlight causing the water temperature to rise to 50°C, what will the measurement error be?What do you think is “ultra clean water?” Why is a sample required to be placed in a water bath for about 20 minutes at 25 deg. C.? Why dry the pycnometer completely? What is the unit of measurement of specific gravity?
- If water with a height of 1.2 m in a manometer is replaced by oil with specific gravity of 0.75, what is the equivalent height?Please answer asap Both a gage and a manometer are attached to a tank to measure pressure. Given the reading on the pressure gage, determine the differential height h of the mercury column. (Round off ONLY the final result to three decimal places. Indicate the unit of your final answer)What volume flow rate in gallons per minute of oil (sg = 0.80) in the system if the manometer deflection h is 250 mm?
- Problem 3. A news broadcaster report that the barometric pressure is 30.40 in of mercury. Calculate the pressure in psia. a. 24.93 psiab. 14.93 psiac. 34.93 psiad. 54.93 psiae. 44.93 psiaf. 4.93 psiaFind the discharge of water through a venturimeter with inlet and throat diameters 300mm x 150mm respectively. A mercury manometer is connected to the inlet and throat which gives a reading of 200 mm of mercury. Take Cd=0.98.1. A mercury barometer at the base of a mountain reads 28.95 in. At the same time, another barometer at the top of the mountains reads 23.22 in. Assuming w for air to be constant at 0.0765 lb per cu.ft, what is the approximate height of the mountain?

What is the smallest interior angle of this triangle in degrees ? 3) The ages of a certain population in a city is normally distributed with mean of 45 and standard deviation of 15. If the city has a population of 5000, how many would you expect aged 20 to 60?Absolute pressure = Gauge pressure + Atmospheric pressureA pressure gauge in a refrigerator system is reading 119.6 pounds per sq ingauge pressure when the atmospheric pressure is 14.7 pounds per sq in (psi).What is the absolute pressure of the refrigerant in that system?Subject : Fluid mechanics Please give me right answer according to the question. A differential manometer containing mercury is attached from the base of the inlet to the throat and to the base of the outlet. Calculate the deflection of mercury in each tube if the head lost from the inlet to the throat is 10% of the velocity in the throat and from the throat to the outlet is 30% of the velocity head in the throat.
