### What are pipes and cisterns?

Cistern: Cistern is a tank for storing liquids generally water and has inlet and outlet pipes to fill or empty itself. Pipe: Pipe is a section of a hollow cylinder for the discharge of water from one place to another. Pipes are generally connected to the cistern/tank for filling and emptying the cistern or tank.

#### How much time will PQ and T will take to empty the full tank?

P and Q are filling pipes which can fill a tank in 15 minutes and 20 minutes respectively. R is an emptying pipe which can empty the full tank in 30 minutes. The 3 pipes are operated continuously one after the other in the order of P,Q and R,each being kept opened for 2 minutes.

What is the formula of time and work?

Important Time and Work Formula Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.

What is the pipe of a tank called?

A pipe is connected to a tank or cistern. It is used to fill or empty the tank; accordingly, it is called an inlet or an outlet. Inlet: A pipe which is connected to fill a tank is known as an inlet. Outlet: A pipe which is connected to empty a tank is known as an outlet.

## How do you solve tank capacity?

To find the capacity of a rectangular or square tank: Multiply length (L) by width (W) to get area (A). Multiply area by height (H) to get volume (V). Multiply volume by 7.48 gallons per cubic foot to get capacity (C).

### In what time can the outlet pipe empty the tank?

An outlet pipe can empty a tank in 24 hours.

#### How much time will a pipe A alone take to fill the tank?

Pipe A alone can fill the whole tank in = 40/1 = 40 hrs.

What is energy formula?

The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh. Unit. The SI unit of energy is Joules (J).

What is mixture problem?

Mixture problems are ones in which two different solutions are mixed together, resulting in a new, final solution. Using a table will help to set up and solve these problems.

## What are the 3 basic types of tanker pipelines system?

There are three basic types of pipeline systems:

• Direct Line system.
• Ring main system.
• Free flow system.

### What are the three basic types of pipeline systems?

This process also involves three different types of pipelines: gathering systems, transmission systems, and distribution systems. Similar to the petroleum gathering systems, the natural gas gathering pipeline system gathers the raw material from production wells.

#### How do I know what size cistern I need?

If your cistern is rectangular in shape, rather than square or circular, you can determine its capacity by the following procedure. Multiply the length by the width by the depth (all in feet) to get the number of cubic feet of storage. Then multiply this figure by 7.5 to get the number of gallons of storage capacity.

How long will it take to empty the tank if both the inlet pipe?

[E]. Tank will be emptied in 16 minutes….Discussion :: Pipes and Cistern – Data Sufficiency 1 (Q. No. 2)

How long will it take to empty the tank if both the inlet pipe A and the outlet pipe B are opened simultaneously?
I. A can fill the tank in 16 minutes.
II. B can empty the full tank in 8 minutes.

How long does it take to empty a tank?

The tank should be empty in about 2-1/4 hours. Variables: h = elevation of tank D = diameter of tank A = orifice area (ft2) G = gravitational acceleration = 32.2 ft/sec2 ∆t = time required to empty tank (sec) The following formulas are based on turbulent flow of a Newtonian fluid through an outlet (orifice) in a tank.

## What is the capacity of tank if all three pipes working together?

All the three pipes working together can fill the tank in 15 minutes. The capacity of the tank is: A. B….Exercise :: Pipes and Cistern – General Questions.

Volume of 1 part = 3 gallons.
40

### Can fill a tank in 6 hours after half the tank is filled three more similar taps are opened what is the total time taken to fill the tank completely?

Explanation: Time taken by one tap to fill half of the tank = 3 hrs. So, total time taken = 3 hrs. 45 mins.

#### What is E mc2 used for?

Mass can be converted into pure energy. This is the second meaning of the equation, where E = mc2 tells us exactly how much energy you get from converting mass. For every 1 kilogram of mass you turn into energy, you get 9 × 1016 joules of energy out, which is the equivalent of 21 Megatons of TNT.

What are 10 examples of mixtures?

Here are a few more examples:

• Smoke and fog (Smog)
• Dirt and water (Mud)
• Sand, water and gravel (Cement)
• Water and salt (Sea water)
• Potassium nitrate, sulfur, and carbon (Gunpowder)
• Oxygen and water (Sea foam)
• Petroleum, hydrocarbons, and fuel additives (Gasoline)

What are the hazards in tanker?

1. Cargo: Cargoes carried on tanker ships are flammable in nature as most of them release some types of gases which may form a combustible mixture composed of hydrocarbons. A flammable mixture contains 1 – 10% hydrocarbon gas by volume and the rest is air.

## How many piping systems are on a ship?

A ship contains a total of approximately 80 separate piping systems. Pumps, blowers, and other mechanisms in the systems may be powered by the ship’s main or auxiliary power systems or by individual motors.
