Two centrifugal pumps P and R are available for use in a pipe flow system and their head-discharge characteristics are as follows. Pump P Pump R Discharge (cumecs) Head (m) Discharge (cumecs) Head (m) 0 40 0 45 0.12 35 0.14 40 0.2 28 0.24 35 0.3 18 0.3 28   The following statements (S1, S2, and S3) pertain to the head and discharge values during actual operation. Neglect losses in the system. Which of the following statements are correct? S1: When the two pumps P and R are connected in parallel, the discharge is 0.36 cumecs corresponding to a head of 35 m. S2: When the two pumps P and R are connected in parallel, the discharge is 0.36 cumecs corresponding to a head of 70 m. S3: When the two pumps P and R are connected in series, the discharge is 0.3 cumecs corresponding to a head of 46 m.
The discharge through a channel of circular section will be maximum when the depth of water is __________ the diameter of the circular channel.
The ratio of the hydraulic radius to the diameter of the channel, for maximum mean velocity of flow in a circular channel, in open channel flow is
The ratio between normal discharge and maximum discharge through a rectangular channel is 32:6, calculate the depth of the channel if the width of the channel is 4m and bed slope, chezy’s constant remains same.
The velocity through a channel of circular section will be maximum when the depth of water is __________ the diameter of the circular channel.
The maximum discharge through a circular channel takes place, when the depth of the fluid flow is __________ times the pipe diameter.
If the ratio of GVF depth to normal depth and the ratio of critical depth to normal are equal to 0.5, calculate the rate of change of depth if the bed slope of the channel is 1 in 1300.
If the velocity of flow through a wide rectangular channel is 2m⁄s and the rate of change of depth is 3×10-5m, calculate the manning’s constant of the channel if the uniform flow depth is 1m and yn=0.6m. Given: Critical depth = 0.5m.
Normal depth in open channel flow is the depth of flow in the channel
