could you please help me calculate theheigth in metres of the fluid at time t= 100s

Petrol (ρ=750 kg/m3) flows through a pipeline with inlet diameter 8 cm and outlet diameter 4 cm. The inlet and outlet gauge pressures measured to be 400 kPa and 130 kPa respectively. Assuming the pipeline to be horizontal and neglecting friction, calculate the outlet velocity (V2) of water by using continuity and Bernoulli’s equation.

A cylindrical container with a massless and frictionless piston is filled with water up to a height h, as shown in the schematic. What mass m should be placed on the piston so that the water flow rate through the opened valve doubles? Consider that piston area A₁ = 0.05 m², valve area A₂ = A1/8, h = 0.9 m, Pwater = 1000 kg/m³, and g = 9.80 m/s². piston area: A₁ m = ? Т h/5 valve area: A₂

A two storey building has two faucets, one in the basement and one in the firstfloor. The maximum water (ρ = 1000 kg/m3) velocity at the basement faucet, when the first floor faucet is closed, is 13 m/s. The faucet diameter is 1.5 cm.Neglect all losses. What would be a maximum height (from the basement floor) for a faucet,to still get a maximum exit velocity of 6 m/s?

Can you help me to solve this problem? Water is siphoned from the tank shown on the Figure below. Assuming frictionless flow, determine the mass flowrate from the tank in kg/s to 2 decimal places. Take atmospheric pressure and density of water 105 Pa to be 1000 kg/m3, respectively.  Gravitational acceleration is 9.81 m/s2

There is a storage tank with a height of 5 m. Initially the tank is empty. The cross- sectional area of the tank is 1m?. There is a hole in the storage tank at a level of 2m from the bottom of the tank. The relationship between the volumetric flowrate through the hole and the level of the tank is q=vh. In addition there are two valves at the top and bottom of the tank for inlet and outlet streams. Suddenly, the two valves at the top and bottom of the tank are opened where inlet and outlet stream volumetric flowrates became 1m/s and 0.2m2/s. a)Determine the time for the liquid level to reach 2m

Water flows through a corner valve at a flow rate of Q=0.75 m³/s . The pressure just upstream of the valve is P₁ = 500 kPa and the pressure just downstream is P₂ = 300 kPa. The inside pipe diameters of the valve inlet and exit are respectively, D₁ = 5 cm and D₂ = 12 cm. If the flow through the valve occurs in a horizontal plane, determine the head loss, h₂ (in meters) and the rate of loss of available energy (in W) across the valve. D2 Di
