Q8. The closed tank shown, which is full of liquid, is acceler ated downward at 1.5g...
A closed tank is filled with water and has a 4-ft-diameter
hemispherical dome as shown in the figure below. A U-tube manometer
is connected to the tank. Determine the vertical force of the water
on the dome if the differential manometer reading is 7 ft and the
air pressure at the upper end of the manometer is 13.6 psi.
Setting up the manometer equation, I found the pressure in the
closed tank to be 2894.4 lb/ft^2, but when doing the...
#3 Consider the manometer shown in the figure below, in which a pressure difference PA-PB exists between the two sides of the manometer. Four liquids are in the manometer with densities Pa, PB, pc and pp and the heights of the columns of liquids are shown in the figure. Gravity is pointing downward. PAT B SE What is the pressure at level "1" in terms of the density of the green fluid, PA and ha? What is the pressure at...
3) As shown in the figure below, water (o 1.94 slugs/ ft') is pumped from a large tank (1) at a rate of 3 ft'/s through a main supply line to the top of an aeration column (2), which is a large free surface open to the atmosphere. The head loss through the supply line is 4 ft. In the acration column, the water is entrained with air as it moves downward via gravity through the column and exits to...
1) Liquid leaked from a damaged tank at a rate of r(t) liters per hour.

-3 A tank full of liquid (p-1000 kg/m ,H-10 kg/(m s)) discharges to the atmosphere (K-0) through a smooth pipe of diameter D= 5 cm and variable length L whose outlet section is at a height h=10 m below the surface of the deposit. Between the deposit and the pipe a globe valve is placed in order to control the flow rate and maintain it at a constant value Q-0.01 m /s. Calculate the maximum pipe length beyond which it...
± Tactics Box 14.1 Hydrostatics Learning Goal:To practice Tactics Box 14.1 Hydrostatics.In problems about liquids in hydrostatic equilibrium, you often need to find the pressure at some point in the liquid. This Tactics Box outlines a set of rules for thinking about such hydrostatic problems.TACTICS EOX 14+ Hydrostatics1. Draw a picture. Show open surfaces, pistons, boundaries, and other features that affect the pressure. Include height and area measurements and fluid densities. identify the points at which you need to find the...
i need help with the postlab questions please
Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
