Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Verify the answer 113kpa. Please show detailed work in a handwritten format. Subject: Mechanical engineering,Fluid mechanics. The Question asks: A 2.5 m tall steel cylinder has a cross sectional area of 1.5 m^2 . At the bottom with a height of 0.5 m is liquid water on top of which is a 1 m high layer of gasoline. The gasoline surface is exposed to atmospheric air at 101kPa. What is the highest pressure in the water?
Question 1: Sally's pet lizard makes a weird groaning noise every couple of seconds. She notices that the number of groans per minute is very regular, but increases as the temperature increases. Further observations reveal that the number of groans per minute actually has a linear relationship with temperature over the normal range of temperatures in the lizard's natural environment. So she decides to make use of her lizard as a thermometer. Sally measures that the number of groans per minute at 10.0°C is 12, and the number of groans per minute at 45.0°C is 31. If she measures that the number of groans per minute in the lizard's usual aquarium is 24, what is the temperature in the aquarium, in degrees Celcius? You can check your answer using the Mastering Physics assignment. Math tip: A linear relationship between two quantities X and Y, means that for a change in X (which we usually call AX), the change in Y is given by AY = m AX, where m is some constant. In the range of X where this…
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
