Weight Loss of an Object in Seawater

Vidhur — Wed, 22 Jan 2025 16:46:20 +0000

The apparent weight loss of an object in seawater is governed by Archimedes’ Principle, which states that the upward buoyant force exerted on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

Weight of the concrete can be found by force formula, i.e.,

Weight of the concrete can be found using the same formula by changing density, then subtracting that value from the above value.

The calculator shows the subtracted value.

isentropic area mach number relation

Problem Statement:

A perfect gas flows isentropically through a nozzle. If the ratio of the nozzle exit to the throat is 3.0, and the exit Mach number is also 3.0, find the specific heats ratio of the gas.

Equation:01

Isentropic Relations:

Isentropic relations are thermodynamic relationships that describe how a fluid behaves during an isentropic process. An isentropic process is a reversible adiabatic process where entropy remains constant.
Isentropic relations are important for analyzing the flow of compressible fluids, like gases, especially when there is no heat transfer or friction. They help predict how pressure, temperature, and density change in a flowing fluid without external heat sources or viscous effects.
The term “isentropic” comes from the Greek words isos, meaning equal, and entropia, meaning entropy. Entropy is a measure of disorder or randomness in a closed system.
In real-world applications, the isentropic process is an approximation because it’s not possible to completely isolate a system. However, the concept is useful for simplifying the analysis and calculation of various thermodynamic processes.

Equation 2:Mach Number

Mach number is calculated by finding the ratio of speed of an object to the speed of sound in the surrounding medium. Mach number is unitless (dimensionless quantity). The formula for calculating Mach number is M = v/c , where M is Mach number, v is the velocity of object (in meters per second, feet per second, etc.)

Measuring Pressure with a Multifluid Manometer

Vidhur — Wed, 08 Jan 2025 12:49:28 +0000

A multifluid manometer is a device used for measuring the pressure of a fluid (typically a gas or liquid) by using more than one fluid to help create a readable scale. These devices often involve the use of liquids of different densities, which makes them useful in measuring a wide range of pressures, including very high or low pressures.

Key Components:

U-tube or Inclined Tube: A tube bent in a U-shape or inclined at an angle is often used to measure pressure. One side of the tube is open to the system whose pressure is being measured, and the other side is open to the atmosphere or a reference pressure.
Fluids: In a multifluid manometer, different fluids (often liquids with varying densities) are used in each leg of the manometer. Common choices are mercury, water, or other liquids, depending on the pressure range.
Measuring Scale: The difference in the height of the fluids in the two arms of the manometer indicates the pressure difference. A scale is marked on the tube to measure this height difference.
