Homework 2

Pressurized eyes Our eyes need a certain amount of internal pressure in order to work properly, with the normal range being between 10 and 20 mm of mercury. The pressure is determined by a balance between the fluid entering and leaving the eye. If the pressure is above the normal level, damage may occur to the optic nerve where it leaves the eye, leading to a loss of the visual field termed glaucoma. Measurement of the pressure within the eye can be done by several different noninvasive types of instruments, all of which measure the slight deformation of the eyeball when a force is put on it. Some methods use a physical probe that makes contact with the front of the eye, applies a known force, and measures the deformation. One non-contact method uses a calibrated “puff” of air that is blown against the eye. The stagnation pressure resulting from the air blowing against the eyeball causes a slight deformation, the magnitude of which is correlated with the pressure within the eyeball.…

Three types of fluids stack in an open tank as shown in the plot.  Select the expression of the gage pressure at location 2, P2(gage)=______       A.     B.     C.     D. patm

A. How fast is the water going out of this pipe? B. What is the pressure of the liquid at the top of the pipe? Assume that the system is exposed to 1.00 [atm] of air pressure. C. What is the maximum height the pipe can go above the drum before water stops flowing out of the pipe? For liquid flow to be continuous, liquid's pressure must not fall before its vapor pressure. Assume that vapor pressure in this case is 2.30[kPa].

Question 1 Gas, 20 "WC 110" 40" S.G 0.88 50" S.G-1.03 10 A differential pressure transmitter is used for the measurement of liquid level in a process vessel (dry leg), as shown. Determine the transmitter pressure reading in "WC? Blank #1: LT = "WC (Include polarity in the answer, blank for positive, - for negative)

True Story! The 1998-1999 Mars Climate Orbiter mission was declared a total loss in1999 as there was a unit conversion mismatch error between Lockheed Martin and NASA. Themismatch was in the thruster force units. NASA used the SI system which called forNewton-Seconds (4.45 times as large) of thrust and Lockheed Martin used Pound-Force Seconds.Calculations placed the Orbiter at 68 miles from the surface as it went into orbit, but it waswithin 57 km of the surface after the breaking maneuver. Any distance from the surface lessthan 50 miles would have caused the Orbiter to crash.a. What was the actual distance of the Orbiter from the surface in miles?b. In percentage, how far off from the calculated 68 miles was the Orbiter?

The final answers( for both) must be correct , Please solve fast & take care.

The speed of the fluid is constant throughout the volume of the pipe. The speed of the fluid is greatest near the center of the pipe. The speed of the fluid is greatest near the walls of the pipe.                         A viscous fluid is flowing through two horizontal cylindrical pipes. The pressure difference P2-P1 between the ends of each pipe is the same. The pipes have the same radius, although one is twice as long as the other. How does the volume flow rate QB in the longer pipe compare to the volume flow rate QA in the shorter pipe? QA is the same as QB . QA is twice as large as QB . QA is one-fourth as large as QB . QA is half as large as QB .

The right side leg of the pictured manometer is open to the atmosphere with a pressure of 1 atm. The left side leg is connected to a closed gas reservoir. The scale is graduated in cm. If the blue fluid in the manometer is gallium, what is the pressure at the gas/gallium interface in the left hand leg?a. 106.9 kPab. 103 kPac. 600 kPad. 5.7 kPa
