Question

PRACTICE: SOLVE THE EXERCISE Calculate the force \( \mathrm{F} \) to apply on the piston \( \mathrm{S} \) necessary to obtain a pressure reading at the manometer \( M \) equal to 0.6 bar (note that 1 bar \( =10 \wedge 5 \mathrm{~Pa} \) ). Data: \( S \) has a circular shape, its diameter is \( D=5 \mathrm{~cm} \); Height of the tank a = \( 3 \mathrm{~m} \); Fluid into the tank : water \( \left(\gamma_{\mathrm{H} 2 \mathrm{O}}=9806 \mathrm{~N} / \mathrm{m}^{3}\right) \). THEORY: ADDRES THE PROPOSED ISSUE Describe how (and why) the pressure distributes in a fluid mass at rest . Consider a devive suitable to measure pressure at your choice and describe it.

PRACTICE: SOLVE THE EXERCISE
Calculate the force F to apply on the piston S necessary to obtain a pressure reading at the manometer M equal to 0.6 bar (note that 1 bar =10 ∧ 5 Pa ).

Data:
S has a circular shape, its diameter is D=5 cm;
Height of the tank a = 3 m;
Fluid into the tank : water (γH 2 O=9806 N / m^3).

THEORY: ADDRES THE PROPOSED ISSUE
Describe how (and why) the pressure distributes in a fluid mass at rest . Consider a devive suitable to measure pressure at your choice and describe it.
