One finish of the tube is connected to the tank and also the other end is opened i.e. **press because of the elevation of the manometric liquid is balanced by the pressure in the tank.You are watching: A manometer is used to measure the pressure of the**

Taking lower point of manometric fluid asrecommendation suggest (Horizontal recommendation line with this),

P=Pa+ρmgh

wright here,

P = Absolutepush of tank,ρm= thickness of manometric fluid, h = column height

**Calculation:**

**Given:**

Patm= 96 kPa,ρ = 0.85× 1000 = 850 kg/m3, h = 55 cm = 0.55 m

Because of this for absolute pressure,

⇒ P= 96000+ 850 ×10 × 0.55

**⇒ P = 100.675 kPa**

**Q1.**A directly 100 m long raw water gravity major is to carry water from an intake framework to the jack well of a water therapy plant. The compelled flow via this water main is 0.21 m3 /s. Allowable velocity via the main is 0.75 m/s. Assume f = 0.01, g = 9.81 m/s2 . The minimum gradient (in cm/100 m length) to be provided to this gravity major so that the forced amount of water flows without any type of difficulty is ___________

**Q2.**An incompressible liquid is flowing at a secure price in a horizontal pipe. From a section, the pipe divides into two horizontal parallel pipes of diameters d1 and also d2 (wright here d1 = 4d2) that run for a distance of L each and then aacquire sign up with back to a pipe of the original size. For both the parallel pipes, assume the head loss due to friction only and also the Darcy-Weisbach friction element to be the very same. The velocity ratio in between the bigger and also the smaller sized branched pipes is _________

**Q3.**Three rigid buckets, shown as in the numbers (1), (2) and (3), are of similar heights and base locations. Additional, assume that each of these buckets have negligible mass and also are complete of water. The weights of water in these buckets are deprovided as W1, W2, and also W3 respectively.
