The depth of water at which the gate rises and permits water to flow under it is to be calculated. Concept Introduction: The force ( F ) acting on a surface due to a fluid above it is defined as: F = ρ g z A .......(1) Here, ρ is the density of the fluid with height z , A is the area of the surface, and g is the acceleration due to gravity. The force that leads any object to float when immersed partially or fully in a fluid is known as buoyancy or buoyant force. It is the result of the pressure differences that acts on the opposite sides of that object when immersed in the fluid which is static. The tendency of any object to resist any kind of change in the velocity of that object is known as inertia.

Interpretation Introduction

Interpretation:

The depth of water at which the gate rises and permits water to flow under it is to be calculated.

Concept Introduction:

The force (F)

acting on a surface due to a fluid above it is defined as:

F=ρgzA .......(1)

Here, ρ is the density of the fluid with height z , A is the area of the surface, and g is the acceleration due to gravity.

The force that leads any object to float when immersed partially or fully in a fluid is known as buoyancy or buoyant force. It is the result of the pressure differences that acts on the opposite sides of that object when immersed in the fluid which is static.

The tendency of any object to resist any kind of change in the velocity of that object is known as inertia.

In a surface coating operation, a polymer (plastic) dissolved in liquid acetone is sprayed on a solid surface and a stream of hot air is then blown over the surface, vaporizing the acetone and leaving a residual polymer film of uniform thickness. Because environmental standards do not allow discharg- ing acetone into the atmosphere, a proposal to incinerate the stream is to be evaluated. The proposed process uses two parallel columns containing beds of solid particles. The air– acetone stream, which contains acetone and oxygen in stoichiometric proportion, enters one of the beds at 1500 mm Hg absolute at a rate of 1410 standard cubic meters per minute. The particles in the bed have been preheated and transfer heat to the gas. The mixture ignites when its temperature reaches 562 C, and combustion takes place rapidly and adiabatically. The combustion products then pass through and heat the particles in the second bed, cooling down to 350 C in the process. Period- ically the flow is…

Propane is burned completely with excess oxygen. The product gas contains 24.5 mole% CO2, 6.10% CO, 40.8% H2O, and 28.6% O2. (a) Calculate the percentage excess O2 fed to the furnace. (b) A student wrote the stoichiometric equation of the combustion of propane to form CO2 and CO as: 2C3H8 + 11O2 → 3CO2 + 3CO + 8H2O According to this equation, CO2 and CO should be in a ratio of 1/1 in the reaction products, but in the product gas of Part (a) they are in a ratio of 24.8/6.12. Is that result possible? (Hint: Yes.) Explain how
