This 30° vertical bend in a pipe having 2-ft diameter carries water at rate of 31.4 cfs. If the pressure pp1 is 10 psi at the lower end of the bend where the elevation is 100 ft, and pp2 is 8psi at the upper end where the elevation is 103 ft, what will be the vertical component of force that must be exerted by the "anchor" on the bend to hold it position? The bent itself weights 300 lb, and length L is 4 ft. and what about in the horizontal direction?

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
