Tanks volume calculation

Calculation of Tank Volume A tank may be a sin e geometrical element, such as a cylinder, a sphere, or an ellipsoid. It may also have a compound form, such as a c inder with hemispherical ends or a combination of a toroid and a sphere. To determine the volume, each geometrical element usually must be calculated separately. Calculations for a full tank are usually simple, but calculations for partially filled tanks may be complicated. 

When a tank volume cannot be calculated or when greater precision is required, calibration may be necessaiy. This is done by draining (or filling) the tank and measuring the volume of liquid. The... 

Here C30 is the starting tank concentration at time t=0 and V0 is the starting tank volume at t=0. Compare the results of the simulation to the analytical solution which can also be calculated with MADONNA. For the constant density assumption, simply set b=0. 

The compositions of gas and liquid samples taken from a separator are given below. The separator was stabilized at 945 scf/STB. Laboratory measurement indicated a separator/stock-tank volume ratio of 1.052 SP bbl/STB. The density of the separator liquid, calculated with procedures given in Chapter 11, is 49.8 lb/cu ft at separator conditions of 115 psia and 100°F. 

The slurry occupies 70% of the total tank volume and the head space occupies the remaining 30%. The mean residence time of the slurry in the lank (which equals the volume of the slurry in the tank divided by the volumetric flow rate of the stream leaving the tank) is 12 minutes. Use this information, the quantities calculated in Problem 12.9, and the specific volume data given below to estimate the volume (m ) of slurry in the tank, the head space volume, and the total tank volume. 

To investigate how changes in impeller speed and impeller size influence on the fluid shear, the fluid discharge velocities from the impeller have been measured and simulated. The maximum shear rate obtained at the fluid boundary, as well as the average shear rate around the entire impeller can be calculated from these data. The maximum shear rates in the tank volume are generally found on the impeller blade. In a baffled tank, the shear rates decrease from impeller tip towards the tank wall and are decreasing with decreasing rotational speed. 

Analysis for adipic acid in both the solid and liquid phase, plus data for the hold tank volume, slurry density, and weight percent solids, provided sufficient information to calculate the inventory of adipic acid remaining in the hold tank. At the end of the run, a second sample was withdrawn from the hold tank and the adipic acid inventory was again calculated. The absolute amount of adipic acid which had degraded during the run was represented by the difference between the initial and final inventories. 

The volume variation over time caused by addition of reagent A into reagent B (present in the tank) is calculated by means of an overall mass balance taking into account the average density p in the system without chemical reaction. Thus ... 

The system consists of a water filled tank that can be pressurized by gas. The tank is connected by a pipe with a valve to the pressure vessel. In the event the LOCA signal is triggered, the tank is pressurized by gas and the valve is opened allowing the water to flow into the pressure vessel. The tank volume and the water flow are calculated to ensure that the core will be kept covered for as long as necessary. The system has two redundant trains, with two triggering valves in each train. 

The total start-up energy demand of the fuel processor was calculated to be 4.2 MJ. It was calculated that this start-up energy demand increased the fuel consumption of a 24-km driving cycle by 14%. The start-up hydrogen demand was very low, a tank volume of only 12 cm, pressurised to 340 bar, was required to power one start-up. 

An office building is heated by oil-fired burners that draw fuel from a 619 gal storage tank. Calculate the tank volume in liters. 

Build a simulation in HYSYS using water with a flow of 20 kmol h at 15°C and 1 atm as the oifly conponent and the Peng-Robinson equation of state as the fluid property package. Use the default tank volume of 2 m and specify liquid flow control on the Liquid Valve page of the tank unit operation. Calculate the flow out of the tank using Equation W2.1, which describes a linear valve, and then Equation W2.2, which describes a nonlinear valve. In both cases, the outlet flow rate is a function of the liquid head on the tank oifly.
