Q.5 A pump circulates water through a closed pipe network connecting a water heater and a heating coil (heat exchanger) in a room. The total length of the pipe is 28 m and the diameter is 32 mm. There are six 90°-elbows and a globe valve in the network. The head loss through the water heater and the heating coil are 1.6 m and 1.2 m respectively. The water flow rate is 0.88 Ls!. The system uses schedule-40 steel pipes with threaded fittings. Calculate the (i) flow velocity and the unit pressure loss in the pipe. (ii) increase in head across the pump. (iii) power input to the pump if the efficiency of the pump is 70%.

The characteristics of a centrifugal pump operating at 1000 rpm is given by H=45-21002. The system characteristics may be represented by H = 28+3200². The units for volume flow rate Q and head H are m³/s and m, respectively. Assume the validity of the pump similarity laws. When one pump operating at 2000 rpm is used, with the system characteristics remaining unchanged, the operating volume flow rate is m³/s.

Q1: A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a distribution system for potable water. A completely filled and pressurized water tank was found with a small leakage (a hole 5cm in diameter) located on the sidewall of the tank, around 5 meters below the top of the tank. Please calculate the velocity of leakage water that discharges to the normal atmosphere. The dimension of the tank is 20-meter in height and 10-meter in diameter. The gauge pressure of the water tank top is 0.1M Pa. The Bernoulli equation is: P₁/pg + V₁²/2g +h₁ = P₂/pg + V₂²/2g +h₂ Gauge Pressure: 0.1 M Pa 5 meters Leakage velocity?
1.) A process fluid (μ = 3 cP, p = 1210 kg/m³) is flowing through a 5.8-cm ID pipe with an average velocity (Uavg) of 2.5 m/sec. Calculate/estimate the following: a) What is the velocity profile from the center of the pipe (r=0 cm) to the pipe wall (r; = 2.9 cm)? b) The length of the pipe (4) is 10 feet. Calculate the pressure drop through the pipe using the Hagen-Poiseuille law. c) Calculate the Reynolds number for this system. d) Is the flow in the pipe laminar or turbulent? e) Estimate the Fanning friction factor (f) in this system. f) What is the pressure drop (AP) in the system if friction is considered?
The pressure of a reactor vessel can be adjusted bychanging either the inlet or outlet gaseous flow rate. Theoutlet flow is kept fixed as long as the tank pressure remainsbetween 100 and 120 psi, and pressure changes are treatedby manipulating the inlet flow control valve. However, if thepressure goes higher than these limits, the exit gas flow isthen changed. Finally, if the pressure exceeds 200 psi, a ventvalve on the vessel is opened and transfers the gas to a storagevessel. Design a control scheme that meets the performanceobjectives.
