Q : Derive the equation for constant rate drying considering all the three modes of heat transfer i.e. conduction, convection, and radiation.

Solution

⸻

        DRAW THE DRYING CHAMBER DIAGRAM HERE

          (Hot gas inlet → Wet solid → Gas outlet)

⸻

Step 1: Moisture Flux

From drying theory:

N = -(Ws/a)(dX/dt)

For constant-rate drying, N is constant, so

t = (Ws/aN)(Xi − Xf)

Where:

N = drying rate

Ws = dry weight of solid

a = drying area

Xi = initial moisture content

Xf =

Inför en 16-årsgräns på sociala medier

Idag använder nästan alla ungdomar sociala medier varje dag. TikTok, Snapchat och Instagram har blivit en stor del av vardagen. Många använder apparna flera timmar om dagen för att prata med vänner, titta på videos eller bara fördriva tiden. Samtidigt har diskussionen om sociala medier blivit större de senaste åren. Fler vuxna och politiker börjar oroa sig för hur unga påverkas. Jag tycker att Sverige borde införa en strikt 16-årsgräns på

**jQuery** is a fast, small, and very popular JavaScript library. Its main motto is **"Write less, do more."** Before jQuery, writing plain JavaScript to make a website interactive required lines and lines of complex code, and it often worked differently in different web browsers. jQuery wrapped all those complex tasks into simple, short commands that work perfectly across all browsers.
Think of it as a handy "shortcut dictionary" for JavaScript.
## The Basic Syntax
Every jQuery command generally follows

1 .a) Length- A longer wire increases resistance because the electricity has to travel farther. A shorter wire decreases resistance because the electricity travels a shorter distance.

1.b)Thickness – A thicker wire decreases resistance because electricity has more space to move through. A thinner wire increases resistance because there is less space for the electricity to flow. 

1.c) Material – Materials like copper decrease resistance because electricity flows through them easily. Materials

Derivatives are financial contracts whose value is derived from an underlying asset such as shares, commodities, currencies, or indices. Common derivatives are futures, forwards, options, and swaps.

Economic Significance of Derivatives

Risk Management (Hedging): Derivatives help investors and companies protect themselves from price fluctuations and reduce financial risk.

Price Discovery: They help determine future expected prices of securities through market demand and supply.

Alfred Wegener (Continental drift) 1912 Proposed continents were once joined (Pangea) and drifted apart Continental shapes, fossils, matching rock types Could not explain the mechanism — rejected at the time

Arthur Holmes (Mantle convection) 1930s Radioactive decay in mantle generates heat → drives convection currents → moves crust. Also suggested seafloor spreading to explain MORs Radiometric dating Still largely theoretical at the time
