Saburo: Hey Mitsuwa Man, recently Mom has been saying "I need to go on a diet," but what is a diet? Mitsuwa Man: A diet means reducing body weight. People go on diets to maintain their health, and specifically, it often involves making adjustments to diet and exercise. Saburo: Oh, I see. Does the pump do something like a diet too? Mitsuwa Man: Actually, it does! While the term diet strongly implies reducing weight, it ultimately also means using energy efficiently. So, the pump is doing something similar to a diet in the sense of using energy efficiently rather than just reducing the weight of the machine. *For more details, you can view the related links.

Saburo: Mitsuwa Man, I went on a trip by Shinkansen the other day! Mitsuwa Man: That’s great! The Shinkansen is an amazing machine made by combining various technologies. It’s surprising how fast it can go. Saburo: Yeah, it was really fast! But the Shinkansen and a pump, they’re not really related, right? Mitsuwa Man: Good question. Both the Shinkansen and a pump have a common role of transporting something from point A to point B. For example, the Shinkansen carries people and luggage, while a pump moves liquids and gases. So, in that sense, even though they are machines from different fields, you could say they share a common role. *For more details, you can view the related links.

Saburo: Hey Mitsuwa Man, how does a pump work? Mitsuwa Man: Good question, Saburo-kun. A pump is a machine that moves liquids, and it often uses motors, air, or engines to operate. Saburo: I see! So with a motor, how does it actually make the pump work? The motor is that rotating thing, right? Mitsuwa Man: That's right. A motor is a device that converts electrical energy into mechanical energy, and it works by rotating something called a shaft. This rotational force is transmitted to the pump using belts or chains, similar to rubber. Therefore, many pumps use this rotational force to spin blades like those in a fan, adding power to the water. *For more detailed information, you can view it through the related links.
