  • CO2 Partial Pressure

    the increase in water vapour pressure, and lower CO2 partial pressure respectively. Consequently, according to Henry’s law, the amount of dissolved CO2 in water is also decreased. Thus, the increase in temperature will increase the kinetics of precipitation, and also reduce the supersaturation of FeCO3 as a result of lesser amount of dissolved CO2 in the water. B. Pressure Effect of CO2 partial pressure (PCO2) is related to solution pH as well. In the condition where scale-free CO2 corrosion occurs, the increase of PCO2 will increase the corrosion rate. This can be explained by the increment of H2CO3 concentration…

  • The Effect Of Stress On Skeletal Muscle Performance

    Exercise induces a number of cardiovascular and respiratory responses to occur inside the body (1). As exercise commences the demand for oxygen rises in order for the body to continue providing energy for muscular function. To do this, oxygen uptake increases linearly to match skeletal muscle demand, until maximum oxygen consumption is reached (2). Ventilation will increase so more oxygen is being consumed and more carbon dioxide (CO2) is offloaded; cardiac output (the product of stroke volume…

  • Lab Report: Moolar Volume Of A Gas At STP

    volume of a mole of H₂(g) is at STP by using gas laws. The hypothesis for the experiment is that if H₂(g) is produced at RT and STP, Avogadro’s law can be used to experimentally determine the amount of H₂(g) because equal gases at the same pressure and temperature have the same amount of particles. In order to find the molar volume, hydrogen gas was produced in a eudiometer tube by reacting magnesium and hydrogen chloride. The results showed that the molar volume of H₂(g) was 27.5L per mole of…

  • Molar Volume Of Gas Lab Report

    lab was to do an experiment to determine the molar volume of hydrogen gas at standard temperature and pressure, or STP. To start the experiment, a beaker was filled with water and then a cage was created with a copper wire. A piece of magnesium was cut and placed inside the cage in order to keep the reaction going until all of the magnesium reacted with the hydrochloric acid. The eudiometer tube was filled with 15 mL of hydrochloric acid and water and then plugged with a one-hole rubber stopper…

  • Numerical Analysis: Initial And Boundary Conditions

    3.3.2. Initial and Boundary Conditions. The pipe is subject to atmospheric pressure Po at time zero this represented initial condition . Boundary condition represented as at the pipe inlet profiles, uniform pressure Pinlet and its value change with concentration of nanofluid [φ%] and inlet temperature T0 = 60 ºC can be measured for all experimental . On the pipe wall, the pressure was atmospheric pressure Po . Moreover, flow and thermal fields are assumed symmetrical with respect to…

  • Reservoir Drive Mechanismss

    Aquifer water under pressure have to expand slightly, hence displacing oil or gas that is in the reservoir toward borehole where the pressure drops. The mechanism only exists and persist only when aquifer better or equal in quality than the reservoir hence having larger volume that reservoir (Brooks & Omoigui, 2012). In addition, aquifer water has to communicate with the surface recharge for a good assimilation report. The water drive shows effectiveness in oil reservoir compared in the gas…

  • Momentum Conservation Lab Analysis

    Now, the liquid flow governing equations are presented to determine the volume fraction of the liquid and its velocity. The capillary pressure at porous media is defined as the difference between pressure in the liquid and vapor phase. Mass conservation for liquid phase is as follow: (18) (∂(εsρ_l))/∂t+∇.(ρ_l u ⃗_l )=S_(g-l) Darcy law can be used for liquid momentum equation in porous media; therefore, momentum equation is reduced and can be expressed by: (19) u ⃗_l=-K_l/μ_l ∇p_l Also, the liquid…

  • Stp Lab

    mole of H_(2(g)) is 22.4 L, it supports Avogadro’s law that one mole of an ideal gas occupies 22.4 L at STP. At the same time, it indicates that a direct relationship exists between volume and the number of moles of gas as temperature and pressure stays constant. One real world application of the importance of this problem is demonstrated when a helium balloon is lighter than an identical balloon filled with air (http://antoine.frostburg.edu/chem/senese/101/gases/faq/everyday-gas-laws.shtml).…

  • Comparing The Pressure And Temperature Of Vacuum Water

    Surface and center temperature of the mushroom, ambient humidity and temperature of vacuum chamber have been measured and recorded by the data logger inside the vacuum chamber (see Fig. 1). On the other hand, the control unit that records the pressure data is located outside the vacuum chamber (see Fig. 1). The measured data saved for each 10 seconds. Before starting the cooling, vacuum pump runs half an hour for stabilizing the system. Experiments carried out for three replicates and the…

  • The Ideal Gas Law

    The Ideal Gas Law relates several variables of state of an ideal gas with the following equation: P V = n R T, where P is the pressure of the gas in atmospheres, V is the volume of the gas in liters, n is moles of the gas, and T is the temperature of the gas in Kelvin degrees. R is the ideal gas constant. The Ideal Gas Law is a combined summary of Boyle’s Law, Charles’s Law, and the Avogadro’s Law. This Law works best under low pressure, room temperature (298K) environments because these…
