-
The water surface profile formed upstream of a dam or weir in a mild-slope channel, where the depth exceeds the normal depth, is the:
सही उत्तर: घ) M1 (backwater) profile
On a mild slope with y > yn > yc, the gradually varied flow profile is M1, the familiar backwater curve behind dams.

The Weber number represents the ratio of inertia force to:
सही उत्तर: ख) Surface tension force
Weber number relates inertia to surface tension; Reynolds uses viscous, Froude gravity and Mach elastic forces.

According to Buckingham's π theorem, a physical problem involving n variables with m fundamental dimensions can be expressed in terms of how many dimensionless groups?
सही उत्तर: ग) n − m
Buckingham's theorem gives (n − m) independent dimensionless π terms.

Chezy's formula for the mean velocity of uniform flow in an open channel is:
सही उत्तर: घ) V = C √(RS)
Chezy's formula is V = C√(RS), where C is Chezy's coefficient, R the hydraulic radius and S the bed slope.

In a rectangular open channel, when the specific energy is a minimum the critical depth equals:
सही उत्तर: क) Two-thirds of the specific energy
At critical flow in a rectangular channel the velocity head equals yc/2, so E = 1.5yc, i.e. yc = (2/3)E.

A Francis turbine is best described as a:
सही उत्तर: ग) Reaction turbine suited to medium heads, with mixed (inward radial to axial) flow
The Francis turbine is a reaction turbine for medium heads; Pelton is impulse (high head) and Kaplan is axial reaction (low head).

When pipes are connected in parallel between two points, which quantity is the same for each pipe?
सही उत्तर: ख) Head loss
In parallel pipes the total discharge divides among the branches, but the head loss between the common junctions is the same for every branch.

-
The head loss at the sharp-edged entrance from a reservoir into a pipe is usually taken as:
सही उत्तर: घ) 0.5V²/2g
The entrance loss coefficient for a sharp-edged (square) entrance is about 0.5, giving 0.5V²/2g.

In pipe flow, the energy gradient line (total energy line) lies above the hydraulic gradient line by an amount equal to the:
सही उत्तर: क) Velocity head V²/2g
The HGL represents p/γ + z, while the EGL adds the velocity head V²/2g.

A pressure gauge reads 150 kPa where the local atmospheric pressure is 101.3 kPa. The absolute pressure is:
सही उत्तर: ग) 251.3 kPa
Absolute pressure = gauge pressure + atmospheric pressure = 150 + 101.3 = 251.3 kPa.
