problem:- A circular tank of diameter 4m contains water up to a height to 5m. Orifice of diameter 0.5m at the bottom. Find the time taken by water:- 1. To fall from 5m to 2m 2. For completely emptying to tank take cd=0.6


 A circular tank of diameter 4m contains water up to a height to 5m.

Orifice of diameter 0.5m at the bottom. Find the time taken by water:-

1.          To fall from 5m to 2m

2.          For completely emptying to tank take cd=0.6

Determine the height of a rectangular weir of length 6m to be built across a rectangular channel. Maximum depth of water on the upstream side of the weir is 1.8 and discharge is 2000 l/sec . Take Cd = 0.6 and neglect end contractions.

what is venturi flume - Campare venture meter and orifice meter.

Campare venture meter and orifice meter. Venture meter:- A venturi meter is a tool used to measure the flow rate of a pipe fluid. It cosist of three parts- (1). A short converging part (2). Throat (3). Diverging part It is based on the principle of bernaulli’s equation. Orifice meter:- It is an instrument used to measure the fluid flow rate through a pipe. It's cheaper than a venture meter device. It also operates in the same way as the venture meter principle. Venture flume A venture flume is a critical flow, open flume with a restricted flow, resulting in a fall in the line of hydraulic grade, producing a critical depth. It is used in very high flow rates flow measurements, generally provided in millions of cubic units.
