Need reliable electrical or mechanical 24hr timer

AI Thread Summary
A reliable electrical or mechanical 24-hour timer is needed for a home project, requiring at least 50 cycles with a cumulative error of no more than ±30 minutes. There is confusion regarding the cumulative error period, specifically whether it applies to 50 cycles over 24 hours. Suggestions for components are sought, but the discussion raises the question of why a standard clock cannot be used instead. Clarification on the specifications and requirements for the timer is essential for appropriate recommendations. The focus remains on finding a timer that meets these precise performance criteria.

It needs to perform at least 50 cycles with a cumulative error of no more than [+\-] 30 minutes. This is for a home project.

Any suggestions of components?

I'm not sure I understand...why can't you use a clock (either electrical or mechanical)?
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
