1. An irregular container, closed at the end, is filled with water (999 kg/m). Consider the opening exposed to the atmosphere at 1 atm, find the pressure at point A. Refer to the figure below. P. atm 0.5 m, 40° 60° 0.4 m 0.4 m 3 m 3 m 2.6 m А. 0.3 m all in meters 0.5 0.5 0.5 2.7 m- 1 m
An airship of 100m3 in size is launched from sea level and it gradually attains height until it reaches the desired altitude. A manometer measuring the gage pressure of the inside filled Helium gas show a reading of 1.2 bar at the altitude of A meters from the ground. Manometer shows reading of 2 bar when it reaches to a height of B meters. Assume; Density of air at point A = 1.00 kg/m3 and at Point B= A = 0.80 kg/m3. You can also assume average density = 0.9 kg/m3 where required. Consider temperature inside the balloon = 10°C and negligible change in temperature during the process. (a) How much payload mass can it carry if the mass of airship itself is 5Kg? Do you expect any change in lifting capacity while moving from point A to point B? (b) Calculate the mass of helium to be expelled out to maintain the constant pressure of 2 bar at point B.
Consider the manometer tube shown in below Figure 1. It is filled with three differentincompressible fluids. The closed end of the tube is connected to a reservoir with aconstant pressure. For this configuration, calculate i) the pressure in the reservoir in kPa, ii) the pressure in the reservoir as gage pressure in kPa, iii) the equivalent height of water, and iv) the equivalent height of mercury.
