Question

Make a control volume around the whole power plat in Fig 1.1 and with the help of Fig 1.2 list what flows of mass and energy are in or out any storage of energy. Make sure you know what is inside and what is outside your chosen C.V. Can you carry 1 m^3 of liquid water? What is the lowest temperature in degrees Celsius? In degrees Kelvin? Describe all forms of energy storage mechanisms from molecular point of view. An apple "weighs" 60 g and has volume of 75 cm^3 in a refrigerator at 8 degree C. What is the apple density? List tree intensive and two extensive properties of the apple. The elevator elevator in a hotel has a amass 750 kg, and it carries six people with a total mass of 450kg. How much force should the cable pull up with have an acceleration of 1 m/s^2 in the upwards direction? A vertical hydraulic cylinder has a 125-mm diameter piston with hydraulic find inside the cylinder and an ambient pressure of 1 bar. Assuming standard gravity, find the piston mass that will create a pressure inside 1500 kPa. A steel tank of cross sectional area 3 m^2 and 16 m tall weighs 10000 kg and it is open at the top, as shown in Figure. We want to float it in the ocean so it sticks 10 m straight down by pouring concrete into the bottom of it. How much concrete should 1 put in? Using the freezing and boiling point temperatures for water in both Celsins and Fahrenheit scales, develop conversion formula between the scales. Find the conversion formula between Kelvin and Rankine temperature scales. A 30-lbm steel gas tank holds 10 ft^3 of liquid gasoline, having a density of 50 lbm ft^3. What force is needed to acceleration this combined system at a rate of 15 ft's^2?

Explanation / Answer

Answer 2 Yes, we can store 1 m³ of liquid water. This is because 1m³ means 1tonn weight that is approximately 950 litres. This is a fraction of which any normal water tankers trucks carry. So, yes it is possible to carry 1 m³ of liqiud water.

Answer 3 Lowest possible temperature in degree celcius is -273.15 degrees celcius.

lowest possible temperature in degree calvin is 0 degrees calvin.

Answer 5 Density is defined as the mass of given substance per unit volume. So,

Density = mass/ volume

Density = 60/75 gm

Density = 0.8 gm/cm³
