ở phía hút của máy bơm, đồng hồ áp suất bourdon ghi độ chân không 40kPa. Áp suất tuyệt đối tương ứng là bao nhiêu nếu áp suất khí quyển địa phương là 100kPa(abs)

Answers

Answer 1

Answer:

Nhiều kỹ thuật đã được phát triển cho các phép đo áp suất và chân không. Dụng cụ được sử dụng để đo áp suất được gọi là đồng hồ đo áp suất hoặc đồng hồ đo chân không hoặc áp kế.

Một "'áp kế"' cũng có thể được đề cập đến một dụng cụ đo áp suất, thường được giới hạn để đo áp suất gần đến khí quyển. Thuật ngữ "áp kế" thường được sử dụng để chỉ cụ thể để các dụng cụ cột chất lỏng thủy tĩnh.

Đo chân không được sử dụng để đo lường áp suất trong chân không mà được chia thành hai tiểu thể loại, chân không cao và thấp (và đôi khi chân không cực cao). Phạm vi áp suất áp dụng của một số kỹ thuật được dùng để đo chân không có sự chồng chéo lên nhau. Do đó, bằng cách kết hợp nhiều loại khác nhau của đánh giá, nó có thể để đo áp suất hệ thống liên tục từ 10 mbar xuống đến 10 -11 mbar.

WHAT DO U MEAN WHEN YOU SAY "V8" ENGINE ???​

Answers

A V8 engine is called that because it is an EIGHT cylinder-piston engine in which the cylinders are arranged in a “V” shape. It is a common engine for large automobiles

Answer:

“A V6 engine is a 6 cylinder engine while a V8 has 8 cylinders. The choice between a V6 and V8 will come down to the power and performance you want from your car.”

When buying a car, there are some things that you need to consider but can be deemed confusing. The V6 versus V8 engine is one of them, and knowing the differences and advantages can be helpful when you are trying to make a purchasing decision.   

 

Simply put, a V6 is a 6-cylinder engine. Whereas, a V8 means an 8-cylinder engine. But, you may wonder what the ‘V’ means in V6 and V8. The ‘V’ represents the way cylinders are arranged in your engine. V-type engines have cylinders placed in a V-like shape, or to put it the other way, in two equal rows. This design is commonly used since it requires less space and can fit in most cars.
