Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\" – we hope you will give it your active support! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying, and the thread will be closed after 1 day ! You get 2 wealth points just for participating, and an additional 3 wealth points if you answer correctly~~~ Question: What type of pipes are used for water supply in homes? cast iron pipe
