This thermodynamics statement is false to say that a basic way to reduce the mean velocity of water flowing through a pipe for a given mass flow rate and density is to decrease the inside diameter of the pipe?

A rigid tank of volume 10 m³ initially contains saturated water vapor at a temperature of 120 °C. Steam at a pressure 1.2 MPa and a temperature of 400 °C enters the tank through a valve in steam line that is connected to the tank until the final pressure in the tank is 800 kPa, at which time the temperature is 200 °C. All kinetic and potential energy effects can be neglected. A schematic of the problem and properties at all state points except state 1 are shown in the figure below. All of the properties at state 2 and the inlet state i are provided on the figure. Initial State in Tank T₁-120 °C, Sat. vapor u₁=? kJ/kg V₁=? m³/kg Pi=1.2 MPa, Ti-400 °C hi-3261.3 kJ/kg V=10 m³ Final State in Tank T: 200 °C, P₂-800 kPa u₂= 2631.1 kJ/kg v₂=0.26088 m³/kg Qout For Question 6: The initial specific internal energy, u1, of the saturated vapor in the tank in kJ/kg is

A tub that contains 1 kg of gasoline at 29 oC received 100 kJ of heat. Calculate the extensive entropy change of the system (tub of gasoline). Report your answer in units of kJ/K using three decimal places. You may assume the process is isobaric, and CP of gasoline is 2.22 kJ/(kg · K)
