At what temperature does air become solid? Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum. Can you make solid […]

Why did we stop using steam engines?
Why did we stop using steam engines? According to the designers, diesel engines could run faster and work longer than steam locomotives. They used a vast amount of energy to build up steam pressure, which had to be discarded whenever the locomotive stopped or shut down. In every week of operation, a locomotive consumed its […]

Does the cutting force increase with the following why a increasing depth of cut B decreasing rake angle?
Does the cutting force increase with the following why a increasing depth of cut B decreasing rake angle? It is logical that the cutting force increases as the depth of cut increases and rake angle decreases. Deeper cuts remove more material, thus requiring a higher cutting force. What is rake angle in machining? Rake angle […]
What is simple Vapour compression cycle?
What is simple Vapour compression cycle? Simple vapour compression cycle is a system where the suitable working substance is used, called as a refrigerant. It evaporates and condenses at pressure and temperature closes to atmospheric conditions. The refrigerant used is carbon dioxide, ammonia etc. Why is multi stage compression with intercooling adopted? Advantages of multi-stage […]
