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.…

bliuzodt to mopolb 9. If machine parts are degreased by means of kerosene as shown in the diagram, how much kerosene make-up is needed per day? How much kerosene has to enter the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine parts, and 60 tons of machine parts are processed each day. Five thousand pounds of kerosene (the 10% solution) are carried away by the machine parts each day but drip off and are caught and put back in the degreasing vat. Two hundred pounds of the 10% solution are lost each day from the vat by evaporation, spillage, or by being carried away.

true or false pleassse faster Saturated steam’s enthalpy EQUATES the vapor enthalpy of steam at that given temperature or pressure. Steam is the BASIC source of energy in the food industry The average latent heat of water at any temperature is EQUAL to difference of the vapor and liquid enthalpies at that temperature Under the wet-steam region, isothermal and isobaric lines moves in the SAME direction Degree superheat is the temperature DIFFERENCE of the superheated steam temperature from saturated steam temperature Water CAN boil in a temperature below 100C LIQUID ENTHALPY also refers to the energy of liquid water The enthalpy of steam plotted in steam chart or tabulated in steam table is reckoned from ABSOLUTE ZERO Steam is STABLE even up to 2000K The SUM of moisture and quality under wet-steam region is equal to 1

Which is is/are NOT TRUE about Capillarity? Select the correct response(s): Temperature will not affect the capillary rise of a liquid If the wetting angle is greater than 90 degrees, the fluid inside a tube will fall. Capillary rise increases as the surface tension increases. In wetting fluids inside a tube, adhesion is less than cohesion. The specific gravity of a fluid does not affect the capillary rise. Dense fluids will rise less inside a thin bore tube A small bore tube will produce a higher capillary rise

QUESTION 2 SOALAN 2 a) The DP Transmitter device is used to measure level as an inferential measurement. When installing the DP Transmitter in an open tank at HP tapping point at 0%, the lower range values (LRV) and upper range values (URV) for the transmitter must be determined in order to properly register 0% at the LRV and 100% at the URV liquid level. By referring to Figure 2, calculate the calibrated range with specific gravity, SG is 1.1 and height, H of the tank is 100mm. Peranti Pemancar DP digunakan untuk mengukur paras sebagai ukuran taabir. Apabila memasang Pemancar DP di tangki yang terbuka di HP titik tirus pada 0%, nilai julat yang lebih rendah (LRV) dan nilai julat atas (URV) untuk pemancar mesti ditentukan untuk daftarkan betul pada 0% LRV dan 100% URV. Dengan merujuk Rajah 2, hitungkan julat yang dikalibrasi dengan graviti spesifik, S.G adalah 1.1 dan ketinggian, H tangki adalah 100mm. Tank open to Atmosphere Махт.
