The sewage when running full from inside, is called internal pressure
The internal pressure if any, causes tensile stress in the pipe material
Pressure sewers are designed to be safe in tension

Pneumatic ejector
Reciprocating pump
None of these
Mean radius of sewer
Difference in heads between two points in circular pipes
Mean of radii in a pipe line of varying cross-sections
Cross-sectional area/wetted perimeter
Decreasing the lever arm
Increasing the total perimeter of bars
Replacing larger bars by greater number of small bars
Replacing smaller bars by greater number of greater bars
Lateral reinforcement in R.C.C. columns is provided to prevent the longitudinal reinforcement from buckling
Lateral reinforcement prevents the shearing of concrete on diagonal plane
Lateral reinforcement stops breaking away of concrete cover, due to buckling
