oterwise the returning water stream can abstract the incoming water jet and hence reduces its efficiency
Pelton wheel could be used to lift water from a lower source (lake or something) to pour into a high place. Another use, it could be used to dig into the earth, the wheel have the shape of a milling cutter, it can open channels in the ground or something. It could also be used to measure the speed of a fluid, if connected to a dynamo meter, the speed of flow could be read via voltage. These are some applications. BY: FAISAL RAFIQUE

AnswerThe "twisted ladder" shape of DNA is called a double helix.
#include<iostream> struct shape { virtual double area () const = 0; }; struct triangle : shape { triangle (double b, double h): base (b), height (h) {} double base, height; double area () const override { return base * height / 2; } }; struct circle : shape { circle (double r): radius (r) {} double radius; double area () const override { return 4 * atan(1) * radius * radius; } }; struct rectangle : shape { rectangle (double w, double h): width (w), height (h) {} double width, height; double area () const override { return width * height; } }; int main() { triangle t (10, 5); std::cout << "triangle with base " << t.base << " and height " << t.height << " has area " << t.area() << std::endl; circle c (5); std::cout << "circle with radius " << c.radius << " has area " << c.area() << std::endl; rectangle r (10, 5); std::cout << "rectangle with width " << r.width << " and height " << r.height << " has area " << r.area() << std::endl; }
The symbol for a steam turbine in engineering diagrams is often represented as a circle with a line through it, sometimes accompanied by an arrow indicating the direction of rotation. In P&ID (Piping and Instrumentation Diagram) notation, it may also be depicted as a rectangular shape with specific annotations. The exact representation can vary, so it's essential to refer to the relevant standards or documentation for clarity.

what ever shape you want them to be.

A hemispherical shape is characterized by its half-sphere structure, with a curved surface that extends in all directions from a central point. This shape is utilized in various applications due to its ability to evenly distribute stress and pressure, making it strong and stable. Hemispheres are commonly used in architectural domes, cooking utensils, and scientific instruments like microscopes and telescopes.
Turbine blades typically have an airfoil shape to efficiently harness wind or water energy. The shape is designed to create lift as air or water flows over the blades, converting kinetic energy into mechanical energy. The specific shape of turbine blades can vary based on factors such as the speed and direction of the fluid flow.
The term "hemi engine" refers to an engine with a hemispherical combustion chamber. The word "hemi" is short for hemispherical, and it describes the shape of the combustion chamber in the cylinder head of the engine. This design is known for its efficiency in allowing air and fuel to flow in and out of the chamber, leading to improved combustion.
Hemi is short for hemispherical. It refers to the heads on an engine that are basicaly domed in shape. It is supposed to provide more compression area allowing more fuel mixture to be ignited at a time thus increasing horsepower. I'm fairly certain I'm remembering the definition correctly.
In order to have thick enough gyri, you would probably have to use rolled manicotti.
"Hemi" is short for hemispherical, which refers to the shape of the combustion chamber. Instead of flat or wedge shaped they're round at the top.

Half a sphere is a three-dimensional shape with a flat circular base and a curved surface extending from the base to a single apex. It is created by slicing a sphere along a plane that passes through its center, resulting in a shape with a hemispherical form.
A parachute with a more rounded shape, such as a circular or hemispherical design, tends to slow down your fall more effectively compared to a parachute with a flatter shape, like a rectangular or square design. The rounder shape allows for better air resistance and drag, which helps to slow your descent speed.
