You can solve this problem using Bernoulli's Equation P1/y + z1 + v2/1/2g = P2/y + z2 + v2/2/2g However, This will only br valid for incompressable fluids, and the specific weight of the fluid is the same at both ends. There can't be any mechanical devices between the two ends, and no energy can be tranferred out or lost by friction.

Why if a gas is present at 27 Celsius its volume becomes doubled when temperature increases to 327 Celsius under constant pressure?
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
What happens to pressure of constant mass of a gas at constant temperature when the volume is doubled?
Pressure is halved when ONLY volume is doubled (n and T are constant).Remember the General Gas Law:p.V = n.R.T(in which R=general gas constant)
What is the amount of electric energy supplied if the current and voltage are doubled?
Energy is measured in the SI unit Joule. One definition of a Joule is one ampere passing through a resistance of one ohm for one second. Thus doubling the electrical current (amperes/amps) passing through a resistance of one ohm for one second will double the energy. As for voltage, given that voltage (volts) = current (amps) times resistance (ohms) then, assuming a constant resistance, the voltage will double if the current doubles. Thus doubling the voltage (and therefore the current) passing through a resistance of one ohm for one second will double the energy (joules).
How must the pressure be changed to double the of gas at a constant temperature?
The absolute temperature must be doubled. (20'C + 273.15) = 293.15K. Doubled... (2) x (293.15) = 586.3K. (586.3K - 273.15) = 313.15'C. It must reach a temperature of 313.15'C in order to double the pressure.
What happens to the volume of gas when you double the number of moles of gas while keeping the temperature the same?
The volume is doubled.

IT means that you arestupid
When you double the force acting on an object and keep the mass of the cart constant the acceleration is?
Doubled.
What happens to the current when the voltage is doubled and the resistance is constant?
I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.
What happen is the potential difference across is double?
If the potential difference between the ends of any conductor is doubled, then the current through the conductor is also doubled.
If the volume of a container of air is reduced?
If the volume of a container of air is reduced by one half the partial pressure of the oxygen with in the container will be doubled. If the volume of a container of gas is reduced, the pressure inside the container will increase.
What is the past tense of double?
Doubled is already the past tense form of double.
What happen to current in a circuit if the voltage in not charged but the resistant is double?
In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.
When the mass of one object increases by a factor of 2 the force of gravity increase by a factor of?
As force of gravity is directly proportional to the mass as mass is doubled then force on it also gets doubled.
How do you use the word double in a sentence?
In the last ten years, the population of the planet has doubled.

What happens to acceleration when force is doubled?
F=ma, if "a" doubles and "m" is the same, the resultant "F" will double. Acceleration is doubled if force is doubled, a1=f/m; a2= 2f/m= 2a1.
What is correct doubled check or double checked?
The answer is "double-checked"
