Chapter 1: Fluids statics assignment
1. A spherical tank of methanol with internal diameter of 0.75m has a mass of 1400 kg. Find the methanol’s weight, density, specific weight, specific volume, specific gravity and dynamic viscosity if kinematic viscosity is 1.5 stoke
Weight, 13734 N
Density,6337.9 kg/m³
Specific weight, 62174 N/m³
Specific volume,1.578×10-4 m³/kg
Specific gravity, 6.34
Dynamic viscosity, 0.95 kg/m.s
2. A cone with base radius of 5 cm and height of 20 cm is filled with oil with specific gravity of 0.85. Determine the length of a cubic steel which its weight is equivalent to the oil weight. Steel Specific Gravity, 7.1
Weight of oil = Weight of cubic steel
x = length of steel cube = 0.0397 m @ 3.97 cm
3. A pressure gauge indicates the nitrogen pressure inside a vessel is 5.2 bar gauge pressure. Determine absolute pressure of nitrogen in term of kilopascal (kPa)
5.2 bar = 5.2 × 105 Pa = 520 kPa
= 101.325 kPa + 520 kPa = 621.325 kPa
4. Determine the absolute pressure at point A, B, C and D in figure 1. Also determine the gauge pressure at point A, B, C and D
Figure 1
93477 Pa
106,320 Pa
Height of air does not significantly boost pressure as compare to liquid, thus
= 106,320 Pa
= 123095 Pa
-7848 Pa, 4995 Pa, 4995 Pa, 21770 Pa
5. Determine gauge pressure at point A, B and C in manometer as shown in figure 2
Figure 2 0 Pa -20012.4 Pa
-21071.88 Pa
6. In figure 3, determine value of X if absolute pressure at A = 125.78 kPa and F = 141.643 kPa. Then,
