RE: Question about pitch of underground drainage pipe. Usually perforated pipes are bedded in gravel. When water accumulates in the gravel it'll bubble up in the perforated pipe and at some point it'll discharge out the end. Perforated pipes do not need to be placed on a design slope like a gravity pipe.
Funeral procession arriving at the church. The coffin is covered with an elaborate red pall. A pall (also called mortcloth) is a cloth that covers a casket or coffin at funerals. The word comes from the Latin pallium (cloak), through Old English. It is also a stiffened square card covered with white linen, usually embroidered with a cross or some other appropriate symbol.
The term is used interchangeably with casket bearer in the modern day. But since you asked, it is a combination of two words-pall -- which is a cloth -- of blanket size, that â¦ has religious significance in many liturgical churches.
