ANS:B - decreases

For 3months, the storage decrease the strength up to @15% after 6months it should be 30% after 1year increase up to 50% of the strength of cement. Period of Storage - Relative Strength (percent) at 28 days
Fresh - 100%
3 months - 80%
6 months - 70%
1 year - 60%
5 year - 50% Because of exposure C3A reacts with environment, gradually strength decreases.

ANS:B - 5 A

Hot wire ammeter indicates rms value .

ANS:B - Toor and Marchello

I'm not familiar with any significant figures or works in chemical engineering or related fields named "Toor and Marchello." It's possible that they may have contributed to the field in some capacity, but without additional context, it's challenging to provide a detailed explanation. If you could provide more information about who Toor and Marchello are or what specific contributions or works you're referring to, I'd be happy to try to help further!

ANS:A - I.D.

The nominal size of a hose pipe is typically specified by its inside diameter (I.D.).

Explanation:

1. Nominal Size:
   • The nominal size of a hose pipe refers to a standard size designation used to describe its diameter. This size is often used for ordering and specifying purposes.
   • For hoses, the nominal size is generally based on the internal diameter (I.D.) of the hose.
2. Inside Diameter (I.D.) vs. Outside Diameter (O.D.):
   • Inside Diameter (I.D.): This is the diameter of the inner hole or bore of the hose through which the fluid flows. It directly affects the flow rate and pressure capacity of the hose.
   • Outside Diameter (O.D.): This is the diameter of the entire hose including its thickness. It is important for fitting the hose into connectors or determining clearance.
3. Thickness:
   • The thickness of the hose wall is not typically used as a primary specification for nominal size. It is important for durability and pressure resistance but does not directly determine the nominal size.
